<i>Anyone sane would look at the evidence and say that Keynesian stimulus works sometimes, and not others</i><p>Sure, and you quoted my qualifier, too. I did say that <i>the question is, "just how wrong?"</i> (Not that there isn't an ideology I favor, but I don't think I was whitewashing to sell it)<p>You'll note that some of the credit in the early 60s has to be given to anti-Keynesians. Kennedy's tax cuts broke from the Keynesian model, and were successful. And if you'll buy into Hayek a little, I'll assert that the WWII boom (no pun intended) can't be credited to following any particular school, but is simply because the economic question is easy when you can get the whole society on the same page, working toward the same goal.
