"You must realize how bad, temporarily, capitalism had become in public opinion. I remember seeing a poll of small town attitudes in local newspapers. They asked questions like "should we nationalize the banking system?" More than half of those editors, about the most conservative group in the world, were in favor of nationalizing the banking system. Father Coughlin, the Detroit demagogue who turned anti-Semitic, complained about "fountain pen money, the perpetrator of great wealth, the money changers in the temple." It was kind of a crude expansionism. Huey Long and "every man a millionaire," or whatever it was. So I would say that Keynes thought of himself as saving the system. And lots of the New Dealers ― original New Dealers, Veblenites, technocrats ― did not like Keynesian economics. They said "that is using palliatives, it's not getting rid of the wicked capitalistic ethos." Keynes told Roosevelt when he came here in 1933 that he needed to spend so much more per month in deficit spending. He gave very precise figures with great self-confidence."
