Hoover was blamed with the bursting of the bubble in '29, even though he introduced Keynesian stimulus. FDR came in with Hoover's plan on steroids and was elected 4 times because he was attempting to fix the economy Hoover "broke." Therefore, basically the same policies the same failures, but it's perception that counts. So as long as Obama has good intentions it really doesn't matter what he does, it will be like Bush's policies in most respects, but the blame will always be on Repubs, conservatives, and free markets, let alone laissez faire economics, because the bubble burst during their tenure, regardless of the fact that the seeds were sown for this disaster in 1971. It seems Keynesians will always hold sway no matter how many times they fail because they are perceived to care, they have "good" intentions, and it appears that they are doing something to "fix" the problems.
I'll see you when the revolution hits the streets.
