Janet Yellen: Economic Inequality in the United States
San Francisco Fed president Janet Yellen thoroughly analyzes the potential causes, consequences, and policy responses to economic inequality in the U.S. Her bottom line?:
Certainly some market-determined income differences are needed to create incentives to work, invest, and take risks. However, there are signs that rising inequality is intensifying resistance to globalization, impairing social cohesion, and could, ultimately, undermine American democracy. Improvements in education are an imperative for reducing inequality and an easily justifiable investment, given its high social return. In contrast, improvements in the social safety net entail costs, even when policy interventions are well-designed from an efficiency standpoint. Even so, in my opinion, they deserve high policy priority. Inequality has risen to the point that it seems to me worthwhile for the U.S. to seriously consider taking the risk of making our economy more rewarding for more of the people.
Here's the speech:
Economic Inequality in the United States, by Janet Yellen, SF Fed President: ...My topic today will be the performance of the U.S. economy... I'd like to focus on ... how the income that has been generated by our economy over the past three decades or so has been distributed among the various income groups, from the top to the bottom.
Questions of income inequality, of course, are not part of the Federal Reserve's ... mandate... Nonetheless, this has been an interest of mine for a long time... Much of my interest in macro policy has been founded on the belief that it can and should improve the lives of the broad range of ... people. I think of this as happening through two channels. First, policies that reduce the frequency and size of the fluctuations in business cycles can spare people the painful disruptions that occur during recessions, or, in the worst cases, tragic events like the Great Depression of the 1930s. Second, policies that succeed in enhancing the long-run growth of productivity should help lift the average standard of living over time.
By many measures, these two channels have been operating extremely well in our economy for some time. In terms of the business cycle, for almost two decades we have been enjoying an era that many economists call the "Great Moderation"; ... recessions have been less frequent, and the swings have been less severe, while, at the same time, inflation has come down to quite moderate levels and itself has been less volatile. Productivity trends also have been very favorable, probably in no small part because of the impact of technological advancements. ...
Given these two developments—more macro stability and more rapid labor productivity growth—it is tempting to conclude that most Americans are feeling "better off." But a glance at the newspapers suggests that this is not necessarily the case. Indeed, poll after poll shows that many Americans feel dissatisfied with the long-term direction of the economy and are worried about the future. ...
Looking beyond the headline numbers on the macro economy provides some clues to the source of this discomfort. In particular, over the past three decades, much of the gain from excellent macroeconomic performance has gone to just a small segment of the population—those already in the upper part of the distribution. As a result, inequality has grown. This inequality, coupled with increased turbulence in family incomes associated with job displacement and restructuring, sheds substantial light on the sources of the disappointment and concern that show up in the opinion polls.
Today I'd like to examine these trends in a bit more detail. ...
Productivity and real wages
A natural place to begin is by looking at average real compensation, that is, average wages plus benefits for an hour of work adjusted for inflation. In the U.S., the growth in average real compensation has roughly tracked growth in labor productivity... When U.S. labor productivity growth slowed sharply and unexpectedly in the early 1970s, and then stayed sluggish for the next 25 years, growth in average real compensation also was sluggish.[3] Then, in the mid-1990s, labor productivity growth surprised us again, only this time, thankfully, on the upside: it suddenly took a big jump up—to over 3 percent at an annual rate—and it has stayed in that vicinity ever since. ... How has this affected average real compensation growth? It has jumped, too, also hitting a 3 percent rate.[4]From this perspective, then, it would seem that things are looking pretty good. However, the public mood does not seem consistent with this view. To see why, we need to dig a little deeper. When we look at data on the distribution of real wages, which constitute the bulk of compensation, we find striking evidence of increasing inequality. For example, economists Robert Gordon and Ian Dew-Becker report that, from 1997 to 2001, nearly 50 percent of productivity gains went to the top 10 percent of the distribution.[5] Importantly, they find roughly the same pattern going back more than thirty years.
Wage inequality
As Figure 1 shows, from 1973 to 2005, real hourly wages of those in the 90th percentile—where most people have college or advanced degrees—rose by 30 percent or more. As I will discuss later, among this top 10 percent, the growth was heavily concentrated at the very tip of the top, that is, the top 1 percent.[6] This includes the people who earn the very highest salaries in the U.S. economy, like sports and entertainment stars, investment bankers and venture capitalists, corporate attorneys, and CEOs. In contrast, at the 50th percentile and below—where many people have at most a high school diploma—real wages rose by only 5 to 10 percent.[7]
Larger ImageWhat I've described so far is the big picture for wage inequality—the major change over three decades. However, an interesting twist on the story has occurred during the last decade, when rapid productivity growth raised the real wages of workers throughout the distribution for the first time since the 1960s. During this period, as Figure 1 illustrates, real wages of the lowest earners—the 10th percentile—actually rose somewhat faster than those in the middle of the distribution. The consequence was that wage inequality among those in the bottom half of the distribution, which had been widening throughout the 1980s, diminished during the 1990s. At the same time, real wages at the upper end continued to soar.[8]
What explains the rising economic inequality?
Although there are a variety of ways to explain trends in wage inequality, perhaps no cut at the data has been more revealing than the differences in real wages by education. As Figure 2 shows, since the early 1980s, the wage gap between college graduates and those with a high school education or less has widened dramatically; the gap between high school graduates and non-graduates also has widened, but less so. Thus it appears that the demand for college educated workers has outstripped the supply.[9] ...
Larger ImageIt's important to recognize, however, that shifts in the return to education and the educational attainment of the workforce cannot fully explain the evolution of inequality over the last thirty years because, even within groups with the same level of education, the gap between high and low earners has widened too. Indeed, the more advanced the degree, the wider the gap becomes. A satisfactory theory must therefore explain not only why the demand for college educated workers has risen but also why "residual" inequality has increased, that is, the part that is unexplained by education and other observable factors.
Skill-biased technological change
A primary explanation has focused on the impact of technology ..., most notably the enormous investments in computers and related technologies. These technologies have changed what workers need to know to do their work, and, indeed, they have changed the nature of the work itself. As a result, there is a greater demand for, and a greater payoff to, workers who have the conceptual and organizational skills to use these technologies most effectively. The necessary skills are more prevalent among college educated workers, so they are in greater demand. However, even among workers with equal educational attainment, skills differ.For example, consider two college graduates with liberal arts degrees: the one who has the skills to use computer power to collect, analyze, and synthesize data may have a distinct edge in the labor market over the other who lacks those skills. Similarly, a machinist with a high school diploma who can use computers effectively will tend to earn more than a coworker who is a technophobe.
This explanation is summed up in the literature by the term "skill-biased technological change." It explains the increased demand for and rising wages of highly educated workers and also rising "residual" inequality because skill differences exist not only across but also within educational groupings. These skill differences are observed by employers and rewarded in the marketplace, but unobservable to researchers.
Globalization
A related factor accounting for rising inequality is the increasing globalization of labor markets. The most basic way in which globalization might affect inequality is through trade, which has raised substantially both imports and exports as a share of GDP. Since the U.S. tends to export goods that use skilled labor intensively and to import goods that use less-skilled labor intensively, increased trade has, on balance, raised the demand for skilled labor and reduced the demand for less-skilled workers in this country. In the 1980s, the impact of globalization was especially pronounced for previously well-paid manufacturing jobs available to U.S. workers possessing a high school degree or less. The result has been job losses and excess supply of low-skilled workers, a situation that has been intensified by an influx of immigrants with less than a high school education.Certainly, globalization has been a factor in the downsizing of several industries that employ less-skilled workers—apparel is a good example. And it may account for part of the increase in inequality over the last thirty years. But it surely can't be the whole story because, for much of the past thirty years, the shift in employment toward an increasingly skilled workforce has occurred across a wide range of industries, whether they were affected by global trade or not. The logical conclusion is that skill-biased technological change has been a dominant force operative across the industrial spectrum.
In recent years, globalization and skill-biased technological change may have been working in combination to particularly depress the wage gains of those in the middle of the U.S. wage distribution... The explanation goes like this. ... Technological change and globalization, especially outsourcing, complemented the skills of highly able workers performing non-routine work requiring problem-solving skills. This explains the continued rapid increase in real wages at the top of the distribution. In the middle of the distribution, however, technology and globalization had the opposite effect—substituting for workers performing routine or repetitive tasks and depressing their wages. At the bottom of the distribution, these developments have had little impact during the last decade. By that time, many low-wage jobs that could be eliminated by technology had already vanished. Most of the remaining low-wage jobs involve manual and service work that cannot easily be automated. This may explain why, as I said, wages in the middle not only rose far more slowly than those at the top, they also rose more slowly than those at the bottom of the distribution during the 1990s....
Globalization in combination with advances in technology, especially communications technology, leads to similar patterns. At the upper end, it has boosted demand for those who have the skills to manage large, complex, global operations. In contrast, an increasing share of domestic jobs in the middle of the wage spectrum has experienced lower demand because companies can now look all over the world for workers able to perform computer programming tasks, communications tasks, and similar jobs—even medical services. At the same time, such outsourcing is far less feasible for manual jobs and for service jobs that require face-to-face interactions and lie at the low end of the wage distribution.
The top one percent
These changes in technology and growing globalization go a long way towards explaining the inequality trends I have described. And there certainly are other factors that have also likely played a role. For example, the fall in the real value of the minimum wage appears to have especially depressed the wages of low-skilled women, while declines in unionization particularly impacted the wages of less-skilled men. However, none of these factors provides a complete and compelling explanation for the rapid growth of real wages at the very top of the distribution, the top 1 percent, which, according to IRS data, doubled between 1972 and 2001.[11]The market forces of changing technology and rising globalization ... may matter to some degree for this group. For example, these forces have substantially increased the size of the markets that American companies serve. This has, in turn, increased the impact of individuals who are at the very top end of the talent and skill distributions—and who tend to be in very short supply. These individuals include so-called superstars, such as top entertainers and athletes, highly successful investment bankers and venture capitalists, and perhaps CEOs, although the latter point is hotly debated. For example, people had a high demand to see Michael Jordan perform—far higher than the demand for even a large number of average NBA players—and technology enabled his performances to be broadcast to a very large worldwide audience at relatively low cost. It's not surprising that he, and other superstars, could earn very large incomes.[12]
The superstar argument is less clear-cut with CEO salaries, in part because a CEO's contribution to the bottom line of a corporation is difficult to measure. Some argue that CEO compensation has been driven up by market forces, like the large increase in the size of many American companies, which increases the potential benefit of hiring the right CEO from the limited pool of candidates.[13]
Another possible explanation is the so-called "tournament" model, in which the CEO's direct contribution to the bottom line is not so much of an issue. This model suggests that large pay differentials for those at the top of an organization function as incentives for lower-ranked executives to compete for those positions, in other words, to work harder in order to win the top spots themselves one day. The resulting increase in effort generates benefits for the company that go well beyond the direct contribution made by the CEO.[14]
While such competitive factors may matter, I cannot ignore the concerns that have been raised of late regarding corporate standards for executive pay-setting. Some observers have argued that corporate boards are increasingly beholden to the CEOs whose salaries they determine; as a result, CEO salaries may be inadequately monitored and sometimes set higher than market conditions or company performance merits. Critics of rising executive compensation also have pointed to inappropriate reliance on compensation schemes that hide payments from shareholders and the market—for example, the backdating of stock options for top executives, which increases executive payouts without properly reflecting the resulting costs in corporate balance sheets. The hidden nature of these payouts may reflect an imbalance in the setting of executive pay relative to shareholder returns and worker pay more generally. Issues like these quite naturally raise concerns for the public and contribute to feelings of dissatisfaction.
Job displacement and income instability
Another contributor to feelings of discontent is the perception that job stability has declined. Globalization and technology appear to have played roles in these trends as well, since they represent changing market conditions that are causing dislocations in previous patterns of labor demand.It's important to note first that our economy is always subject to large amounts of job turnover. Indeed, this is one hallmark of a dynamic, flexible economy, and it is not necessarily a bad thing on net. Data on worker flows—movements into and out of jobs—indicate that about 1 out of 3 job matches are dissolved each year, with a comparable rate of worker matching to new jobs.[15] Over half of this job churning is voluntary in nature, reflecting worker desires to find a job with higher wages, better working conditions, or a different location. Moreover, the degree of job creation and destruction has declined somewhat over the past 15 years, creating a picture of a more stable labor market.
However, involuntary displacement from permanent jobs, due to layoffs or downsizing, is important and has been on the rise over the past two decades. In particular, rates of worker displacement are up relative to measures of overall labor market conditions, such as the unemployment rate. ...
In addition, the distribution of displacement has shifted towards the highly educated: workers holding a college degree saw nearly a 50 percent increase in their displacement rates between the early 1980s recession and the most recent one in 2001, while workers with a high school degree or less actually saw a slight decline in displacement rates. So, more educated workers are seeing erosion of their job security relative to their less-educated counterparts. Of course, job displacement still remains a more significant issue for low-paid workers, but the instability that they have always faced has increasingly spread to higher-income groups.
Involuntary job loss frequently inflicts dire consequences, which have grown more severe over time. Involuntary job losers typically are unemployed for at least four months, about 70 percent longer than individuals who enter unemployment voluntarily. As such, the rising share of permanent job losers among the overall unemployed has helped keep the typical length of an unemployment spell stubbornly high over the past few decades.[18] The picture looks even gloomier when you recognize that some job losers withdraw from the labor force and are no longer counted as unemployed, so their observed unemployment spells understate the severity of the jobless experience. Put these factors together and it's clear that periods without earnings can be quite lengthy and costly for job losers. Moreover, when displaced workers do find new jobs, they're taking a pay cut of about 17 percent on average. The size of this wage loss in the early 2000s was the highest in at least 20 years.
Job displacement also has adverse consequences for health insurance coverage. Research shows that job loss substantially reduces access to health insurance over extended time periods, and this effect is only partially offset by federal COBRA guidelines, which require employers to make continued coverage available—at its full cost—to separated employees.[19] The connection between displacement and the loss of insurance coverage reinforces a more general trend towards declining coverage through employment-based health insurance programs. For example, between 2000 and 2005, health coverage through employer-based programs fell about 4 percent nationwide, representing a loss of health insurance for several million Americans that was only partially offset by increased coverage through government-provided insurance.[20]
Given the increase in job displacement and earnings losses that I described above, it is not surprising that yearly fluctuations in individual earnings and family incomes have increased sharply since the 1970s.[21] Indeed, between the 1970s and the early 2000s, the gaps between the highs and lows in a typical family's yearly income have risen substantially. ... Among families seeing declines in annual income, the size of the typical loss has increased: for example, the chances that an American family will see at least a 50 percent drop in its yearly income has more than doubled since the early 1970s, rising to about one in six families in recent years.
The increased risk associated with these income fluctuations is likely to reduce perceived well-being quite substantially, even if family incomes on average are growing over time. As with the risk of job loss, these income risks are most severe for less-educated Americans. However, during the 1990s, income instability rose relatively more for families with high educational achievement, consistent with the spread of involuntary job loss to highly educated individuals.
Policy options
My focus thus far has been on the problems facing Americans in the labor market and not on potential solutions. It is natural to ask, then, whether anything can be done to alter these disquieting trends. Since technology and globalization have been identified with growing inequality, it might seem natural to look at these areas for possible solutions. While I sometimes feel like smashing my own computer, I wouldn't recommend this as a national policy! However, it's not uncommon to hear proposals to put up barriers to trade as a way to mitigate economic disruption and inequality. I don't think that is the way to go. By providing for specialization in production across countries, trade enhances the size of the economic "pie" here and abroad, and in doing so, enhances overall economic welfare. I think we should look to other policy tools to address inequality, and I will attempt to provide a useful overview of some key considerations.I will begin with education. There can be little doubt that programs that support investment in education, broadly conceived, are worthwhile. Increasing skill has been a significant source of productivity growth. ...
But investment in education takes resources, which complicates the debate: the resources are limited and to a large degree should be directed to where they will pay the highest return. At the college level, one possibility is just to "let the market work." If college pays off, more young people will enroll. Indeed, the rising returns to education at the upper end of the earnings distribution did precede an increase in college attendance through the mid-1990s... Since then, however, despite further growth in the returns to college and advanced degrees, college attendance has flattened out. ...
Does this imply that the highest priority for public funding for education should be the college level? Not necessarily. There certainly is a lot of public discussion by educators and politicians about problems with the quality of K-through-12 education in the U.S., and international comparisons show that American students rank relatively low on standardized tests in science and math, the very kinds of skills that earn higher rewards.
But there is yet another contender for the scarce public funding for education. Recently, researchers led by James Heckman from the University of Chicago have argued that these funds should be targeted at even younger children.[23] Family background factors are critically important in student achievement, and recent evidence suggests that the cognitive and social skills associated with college attendance are developed very early in life. ... As such, programs to support early childhood development, such as preschool programs for disadvantaged children, not only appear to have substantial payoffs early but also are likely to continue paying off throughout the life cycle.
But what about struggling adults, especially those who find that their skills have become outmoded due to technological change or globalization? Should the highest priority for public funding of education be the expansion of federally subsidized retraining programs, such as those associated with the Job Training Partnership Act, the Comprehensive Employment and Training Act, and the Job Corps program for disadvantaged youth? Some researchers, such as Alan Krueger of Princeton University, view the outcomes of these programs as evidence that training investments often have high returns, especially for the economically disadvantaged, who cannot finance educational and training investments on their own.[24]
Proponents of this view argue that these programs, which have been sharply curtailed over the past few decades, should be revived. .... At this point, ... the evidence is unclear regarding the exact conditions under which adult education and retraining programs are cost-effective. However, it seems reasonable to consider providing workers buffeted by powerful economic forces a fair shot at retooling and finding new careers.
Beyond education and training, the United States has long deployed an array of policy tools to combat inequality and diminish economic insecurity. One example is the earned income tax credit... Unemployment and disability insurance cushion family income in the face of job loss and illness, while Social Security shelters many elderly households from poverty. Indeed, inequality in consumption among U.S. families is notably lower than inequality in pre-tax income due to these programs... The real question is whether government should and can do more.
To assess the value of and potential need for additional government intervention, it is instructive to draw some comparisons between the U.S. and other countries. In regard to inequality, over the past few decades it has risen more in the U.S. than in most other advanced industrial countries in the ... OECD. Indeed, by most measures, the U.S. ranks near the top (some might say the bottom) in terms of household income inequality. The inequality gap in the United States is associated with higher levels of overall and child poverty relative to a majority of OECD countries.[25]
This high and growing level of relative inequality in the U.S. reflects, in part, differences in the "social safety net." Among the 30 OECD countries, the U.S. ranks above only Mexico, Korea, and Ireland in gross public social expenditures as a share of GDP spending, and it does the least to target government taxes and transfers towards moving families out of poverty. Not surprisingly, outcomes such as infant mortality and life expectancy are worse in the U.S. than in most advanced industrial countries. As for workplace protections, unemployment insurance in the United States replaces a smaller share of income and offers benefits of shorter duration, while the minimum wage is quite low relative to average wages in the U.S. Moreover, U.S. firms face far fewer restrictions in their ability to fire or lay off workers than do firms in most other OECD countries.
Other countries' efforts to mitigate inequality and provide a safety net may come at a price, however, since these efforts may hinder job growth and intensify unemployment, especially for young and less-skilled workers. Indeed, over the past two decades, unemployment rates generally have been higher in other advanced countries than in the U.S. Heeding this lesson, some European countries have recently taken steps to reduce the distortions associated with generous social insurance programs and employment protections. For example, some are following the U.S. lead, placing less emphasis on policies that discourage hiring and more on programs like the earned income tax credit. By contrast, the U.S. has done little to move closer to the European model of social protections and the reduction of inequality and poverty.
Conclusion
This comparison of the U.S. and other advanced industrialized countries, though just a sketch, is suggestive. The possible responses to rising inequality do not boil down to "either/or" kinds of solutions. Rather, these responses range along a fairly wide continuum, reflecting the tradeoffs that policymakers face between efficiency and equity. Certainly some market-determined income differences are needed to create incentives to work, invest, and take risks. However, there are signs that rising inequality is intensifying resistance to globalization, impairing social cohesion, and could, ultimately, undermine American democracy. Improvements in education are an imperative for reducing inequality and an easily justifiable investment, given its high social return. In contrast, improvements in the social safety net entail costs, even when policy interventions are well-designed from an efficiency standpoint. Even so, in my opinion, they deserve high policy priority. Inequality has risen to the point that it seems to me worthwhile for the U.S. to seriously consider taking the risk of making our economy more rewarding for more of the people.1.

I think Lady Day said it best;
Them that's got shall get, Them that's not shall lose
So the Bible says and it still is news
Mama may have papa may have
But God bless the child, that's got its own, that got its own
Yes the strong get more, While the weak one fades
Empty pockets don't ever make the grade
Mama may have papa may have
But God bless the child, that's got his own, that got her own

I'm fascinated that there's a recognition of the problem of income inequality in the U.S. after so many years of neglect in attention by those who should know better.

Good job of diagnosing the problem.
No real prescription.
Education and job training are not making a dent in the problem.
So now what?
Election day!

Making the economy more rewarding for more of the people is a "risk" for the U.S.? Whoa!

"the tradeoffs that policymakers face between efficiency and equity"
Do you suppose that policymakers ever face 'tradeoffs' between efficiency and INequity???
Janet is from California. Maybe she'd like to tell us about the tradeoff faced by policymakers, who decided that shipping several billion dollars from the utility ratepayers of California to multimillionaire Bush supporters in Texas was a good idea.
Does paying a Fortune 500 CEO several tens of millions or more per year constitute a tradeoff with efficiency?

She seems clueless. She presents a plot on wage disperion due to education, but she fails to notice that even for workers with advanced degrees, wages are not keeping up with gdp growth (25% vs 50% real gdp). As San Francisco Fed president, she should be looking at the effects of fed policy of slowing the economy every time wages go up, in order to stamp out inflation. We already have enough high school advisors telling students that everyone should go to college.

If you want less inequality the fastest, and perhaps the only way, is simply for the government to transfer money from the rich to the poor. It can and has been done in many places, the UK being one (until recently?). In the US this is "socialism" and therefore politically impossible. At least up to now. In short, it is a political question more than an economic one.

What about the effects of speeding up the economy everytime else? Last I checked, assets and capital goods were not even included in the CPI, never mind "core inflation".

Janet Yellin's points are well taken, and I think "Skill-biased technological change" could be unwrapped a little further. On the charts, the lines start to diverge at the very beginning of the 1980's, just after personal desktop computers were introduced. Since then, we have seen two things happen simultaneously: (1) The growth of the computer industry was a source of fantastic new top incomes, because the production of hardware and software is accomplished by relatively few people, (and further, the software is a non-rivalrous good,) yet these products are in demand at almost every other location in the economy -- gathering, to this relatively small number of people, a lot of income. (2) At almost all of those locations where the computer products are used in business, they disintermediate old ways of working; flatten management hierarchies, etc. The final result is to reduce the cost to consumers, and open new vistas for economic growth -- but the first result is to throw people out of high-paying jobs, moving them toward the manual service industries -- and substituting a LESSER NUMBER of computer-skilled technicians getting the higher pay.
For the future, computers can do marvelous things, and their uses in scientific research are likely to help us invent new things for economic growth -- in energy efficiency, for example. That will favor certain incomes. But the computer industry itself is turning into a sort of low-margin standardized commodities business, and the major softwares have shaken-out to just a few; while simultaneously, the effect of computers on general business productivity may be only a one-time shot in the arm. So the effect of "skills-biased technological change" on increasing inequality could slacken a little, or a lot. Look at her charts after 2000 or so: the growths in incomes, and perhaps the widening of inequality, now appear to flatten. This could be Bush economic policy, but maybe not.

In a recovery first you see productivity growth, which is followed by employment growth, and finally by wage growth. Since 2003 we have had about 10% increase in productivity, but only now are we seeing wage growth. Because wages are growing faster than the current productivity growth, it is called inflationary. A lot of economist are now predicting the fed will raise rates to slow the economy to prevent "inflation", which will cut short the period of wage catch up. Look at the graph showing the change in income share of gdp (no cpi correction) at
http://www.visualizingeconomics.com/2006/10/17/share-of-gdp-99th-95th-90th/
There has been a slow steady decline for the last 30 years from the income share that was relativly constant from WWII to the mid 70's.(totaling about 25%)

Ah ha, collective intelligence wins again. Passingly strange this; this continuous separation of people from the economy by economists.

Since the Fed _defines_ inflation as a change in the core CPI index, they have no choice but to raise rates when their monetary expansion finally feeds through to wage increases. What matters to the Fed is _consumer price_ inflation - it looks like they have no problem with inflating the price of assets or higher-order goods. While I'm not sure this increases inequality, some economists are concerned about malinvestment and speculative bubbles. Do you have any alternative policy in mind?

georgist:
Maybe the use of fiscal policy (tax increases) to control inflation would help. I would balance federal budget except during recessions, since deficits are inflationary. Also inequality seemed not to grow before we started running large deficits. Other than that, if I were a power at the fed I would put resources into looking at the connection with monetary policy. Perhaps it is also related to too much stimulation before the peak.
Looking at the graphs, it is hard to believe there was not some change in our economy in the mid 70's that has suppresed wage growth for the last 30 years. Most explaination for inequality growth do not have the right time dependance. Concentrating on the income of the rich is is not useful. Their reported incomes vary with tax policy, capatal gains etc. so no clear pattern can be seen. If wages do not keep up with productivity growth, I think you can assume that the difference is going to to people whos income is not obtained from wages.

there has never been a country on the face on the face of the earth at any time with a more materially prosperous population (rich or poor). I happened to know a person, when i studied in the US, who was black, female, single with children, chronically unemployed, no bank account, and an income under $15,000. This would definitely qualify as poorest of the poor under normal statistics, yet this woman enjoyed a standard of living few middle class people can afford in most developing countries. For example such things as: having clean water and proper sanitation in the house, A/C, fridge, cable TV, and computer with internet access. Plus the enough to buy food and clothes.
Somehow, my own income as a student was also around 15K, and after 3 years i managed to save up enough to buy a new car. I certainly felt underpaid for all the teaching i did, but definitely not poor.
on the other hand, a computer science professor friend of mine, making 110K, constantly wines about having not enough money. go figure...
bottomline is, life at the bottom of the US social ladder is tough: people have to struggle with crime, racism, bad schools, obesity... but lack of money to survive is not one of them. A bit of money cant buy you equality any more than it can buy happiness!

k- Don't generalize from your own experience or your friend's. And don't excuse the system for being incompetent.
After all, in a developed country, your friend may have had health care, child care, a job or job training.

Bruce's retort sticks to my pants: Making the economy more rewarding for more of the people is a "risk" for the U.S.? Whoa!"Whoa!" [Possibly new-fangled varient of "Whoa Nelly" often used when the brakes fail. (Ok, and we got it from the cowboys who just wanted to talk to their horse about that braking. You try it right now and tell me if you don't feel like "neighing" and "whoaing" all day long.) Personify everything, people, esp when the brakes start failin.]
Such a delicate matter for Janet, clearly on one side of that disturbing (really?) inequality, to not be distracted by any cowboys and their "Whoa!"s.
I can see it now at the WH press releases. Instead of all those difficult questions and the difficulty of scheduling them, the press just responds with a herd of "Whoaaa"s.
Good therapy for everybody...gets my morning going that's for sure..."Whoaaaa, Nelly".

Ok people, where exactly is Janet Yellen in this income distribution and does her education level have all that much (anything?) to do with that un-cowboyish placement?
And do we want to hear from joan's son who neva made it outa high school for a "fair and balanced" perspective? Or joan's whip-smart daughter currently practicing brain surgery who nonetheless might take a moment or two or her time to set us and our cerebral cortices on that veritable path to the Truth?
At what point in this escalating disparity do we (dullards to brain surgeons) [but non-upper escheloners] demand a closer look at that upper layer, (1%, or is it 0.1%? or?) and barbeque their little backsides (anything less and we will be tricked again only to find ourselves with nothing for the BBQ)?
Are we expecting a Fisher-like admission from the 400 Club that they made a mistake and now they have their work cut out for them? I'm wearing my fire-retardant suit to the BBQ, you?

Do advanced degrees make people rich, or can rich people afford (opportunity costs) to get more advanced degrees?
Of course the really rich get honorary degrees, after they become rich.
The schools hope they will eventually get around to paying for them.
This proposition indirectly implies something about the disribution of
intelligence (i.e. that poor people tend to be more stupid, at birth) when
in reality it only says something about the distribution of advanced
degrees, which is an entirely different subject. But if all you have to
sell is education, ...

As economics Nobel laureate Bill Vickrey was known to observe, this analysis would benefit from an application of the ideas of Henry George.
Yes, education may play a role in determining who is impoverished, and so may globalization. But when we try to tweak things in either of those areas, we aren't getting at the larger underlying issue, the major cause of poverty, which is a structural issue.
We have permitted the privatization of the economic value of all sorts of things which rightly should be treated as our common property. The effects of this privatization are huge and pervasive.
Beyond the direct effects of that privatization are the indirect effects, which reach into many of our most serious problems -- urban sprawl, with long commutes, limited leisure, unnecessary pollution and energy usage; low wages, with people chasing jobs instead of jobs chasing potential workers; unaffordable housing (in California, even the realtors' organization has given up reporting affordability each month!); children growing up in situations where family income doesn't begin to meet their most simply defined needs; mounting consumer debt at high interest rates; inability to save toward retirement or even a down payment; marriages affected by struggles over money.
The encouraging news is that there is a way to change this, and it is not all that complex. It is not a new idea -- the best selling book on political economy laid it all out over 125 years ago -- and, like the law of gravity, we ignore it at our peril.

It is important to take into account the cost of employee benefits such as health insurance and pensions in any wage inequality study. While take-home pay inequality certainly has increased, the inequality trend is tempered by the fact that the cost of benefits---which make up a higher percentage of the worker's total compensation for lower- and middle-class individuals---has increased even more over the past few decades.
