quote from Foley on HuffPo)...
I don't disagree with any of that, but it is worth asking when this time was that discretionary fiscal stimulus as a tool of macroeconomic stabilization was alive and well. Famously, the United States didn't actually implement a massive program of deficit spending to stabilize the economy in the 1930s. Looking back at the Roosevelt administration what we have is not a Keynesian policy, but a Keynesian interpretation of the trajectory of policy. Monetary expansion leads to big growth in 1933-36, then fiscal and monetary contraction creates a new recession in 1937, and then eventually massive deficit spending to fight World War II had the effect of eliminating unemployment and excess capacity. That’s a Keynesian story. There’s a Keynesian analysis. But obviously the policy was "fight the war" not "deficit spending reduces unemployment."
Then we had a long period when it was all about the Fed setting interest rates and automatic stabilizers. Then we had the current recession, we had the stimulus bill that economists who believed in stimulus said was too small, and now we have austerity-mania. There hasn’t been, as best I know, any time in which discretionary fiscal stimulus was, in practice and by intention, used on the scale that the theory suggests.
I think our mythologizing of FDR is not quite as historically broken as the GOP's mythologizing of Reagan (and we have more of an excuse since it was 80 years ago), but it gets close sometimes. The WPA/CCC/etc. never got unemployment below 15%, and even that was with a biased sampling method that basically ignored women, African Americans, and many Latinos who wanted work but couldn't find any (the collusion of FDR with the white supremacist wing of the Democratic party to pass the New Deal is itself an interesting story).
I agree with Y. that the monetary side of the early New Deal was bigger than the fiscal side, and that tends to be ignored. But anyways, I guess my real problem is that coming at this problem with preconceived notions of what the only solution can be is a bad thing -- even FDR jettisoned his campaign promises (he ran against the progressive incumbent Hoover saying that Hoover was interfering too much with the business cycle) when the economic and political realities hit the fan.
