Why has public investment collapsed?:
Build We Won’t, by Paul Krugman, Commentary, NY Times: You often find people talking about our economic difficulties as if they were complicated and mysterious, with no obvious solution. ... The basic story of what went wrong is, in fact, almost absurdly simple: We had an immense housing bubble, and, when the bubble burst, it left a huge hole in spending. Everything else is footnotes.
And the appropriate policy response was simple, too: Fill that hole in demand. In particular, the aftermath of the bursting bubble was (and still is) a very good time to invest in infrastructure. ... Since 2008,... our economy has been awash in unemployed workers ... and capital with no place to go (which is why government borrowing costs are at historic lows). Putting those idle resources to work building useful stuff should have been a no-brainer.
But what actually happened was exactly the opposite: an unprecedented plunge in infrastructure spending. ... In policy terms, this represents an almost surreally awful wrong turn; we’ve managed to weaken the economy in the short run even as we undermine its prospects for the long run. Well played!
And it’s about to get even worse. The federal highway trust fund ... is almost exhausted. Unless Congress agrees to top up the fund..., road work all across the country will have to be scaled back just a few weeks from now. If this were to happen, it would quickly cost us hundreds of thousands of jobs, which might derail the employment recovery that finally seems to be gaining steam. And it would also reduce long-run economic potential.
How did things go so wrong? As with so many of our problems, the answer is the combined effect of rigid ideology and scorched-earth political tactics. The highway fund crisis is just one example of a much broader problem. ... The collapse of public investment was ... a political choice.
What’s useful about the looming highway crisis is that it illustrates just how self-destructive that political choice has become. It’s one thing to block green investment, or high-speed rail, or even school construction. I’m for such things, but many on the right aren’t. But everyone from progressive think tanks to the United States Chamber of Commerce thinks we need good roads. Yet the combination of anti-tax ideology and deficit hysteria (itself mostly whipped up in an attempt to bully President Obama into spending cuts) means that we’re letting our highways, and our future, erode away.
