1938 again?

Paul Krugman, "1938 in 2010," New York Times, 6 September 2010.

Now, we weren’t supposed to find ourselves replaying the late 1930s. President Obama’s economists promised not to repeat the mistakes of 1937, when F.D.R. pulled back fiscal stimulus too soon. But by making his program too small and too short-lived, Mr. Obama did just that: the stimulus raised growth while it lasted, but it made only a small dent in unemployment — and now it’s fading out. . . .

Paul Krugman has been warning about this possibility for two years, and he says it is now showing signs of happening.
