Statement on the 2016 Social Security Trustees Report: The 2016 Social Security Trustees Report is little changed from the 2015 Report. It shows a small decrease in the projected 75-year shortfall of 0.02 percentage points. Changes in the disability program, along with small changes in projections more than offset the increase of 0.6 percentage points due to shifting the projection period by a year. (The new projection adds 2093, a year with a large projected deficit, and loses 2015, a year with a surplus.) While reporters and politicians routinely focus on the projected shortfall, what will matter far more to the people covered by Social Security is the projected growth in real wages and their distribution. As has been pointed out, almost 40 percent of the projected shortfall in the program is attributable to the upward redistribution of income over the last four decades. This has pushed a larger share of wage income over the taxable maximum. For this reason, the finances of the program are directly affected by the distribution of income. ...
This means that workers have vastly more at stake in whether they will receive their share of wage growth over this period, than whether it is necessary to raise the Social Security tax rate at some point. ... (Of course any shortfall in Social Security could be covered through other mechanisms than increases in the payroll tax.)
This is the last Trustees report of the Obama administration. For this reason, it is worth comparing the changes with the last report of the Bush administration. The 2008 Trustees Report showed a considerably smaller projected shortfall for Social Security. It projected a shortfall of 1.70 percentage points for the years 2008–2082. This figure has increased to 2.66 percentage points in the 2016 report. Roughly half of this increase is attributable to the change in the projection period. Moving the period out eight years added approximately 0.48 percentage points to the projected shortfall. The other half of the increase in the gap was due to the Great Recession. This reduced employment and wage growth, leaving both far below the projections in the 2008 report. This is a clear warning as to the importance of the strength of the overall economy for the health of Social Security.
The positive side of the picture is that the projected shortfall in the Medicare program is now much smaller than had been projected in 2008. At that time, the Trustees projected a shortfall in the program equal to 3.54 percent of payroll. This brought the combined projected shortfall for the two programs to 5.24 percent. In the most recent report, the projected shortfall for Medicare is just 0.73 percent of payroll, bringing the combined projected shortfall to 3.39 percent of payroll.
This means that the longer term shortfall projected for these programs together is now considerably smaller than when President Obama took office. The reason for the decline in the projected Medicare shortfall is a slower projected rate of health care cost growth. This is undoubtedly attributable in part to changes implemented as a result of the Affordable Care Act (ACA). While the size of the impact of the ACA on health care cost growth can be debated, it is clear that the combined finances of these programs looks better in 2016 than when President Obama took office.
