A number of people have asked me to weigh in on David Brooks’s piece today. Sorry, not gonna do a tit-for-tat. Let me instead just make a more general point.

All around, right now, there are people declaring that our best days are behind us, that the economy has suffered a general loss of dynamism, that it’s unrealistic to expect a quick return to anything like full employment. There were people saying the same thing in the 1930s! Then came the approach of World War II, which finally induced an adequate-sized fiscal stimulus — and suddenly there were enough jobs, and all those unneeded and useless workers turned out to be quite productive, thank you.

There is nothing — nothing — in what we see suggesting that this current depression is more than a problem of inadequate demand. This could be turned around in months with the right policies. Our problem isn’t, ultimately, economic; it’s political, brought on by an elite that would rather cling to its prejudices than turn the nation around.
