BTW last time i checked, the Depression of 1920 was still the deepest depression in history. And we recovered from that very quickly compared to the economic downturns that werent as deep but which had politicians trying to fix it with government intervention.
Oh, the Right Wingers LOVE the Depression of 1920, because it's the only one that makes the "Case" that Recessions can be solved by cutting taxes and no government programs.
Of course, they only tell you half the story.
To recap, the Depression of 1920 occurred because after WWI, there was huge deflationary effect on the currency. The whole world was shifting its economy from war material production and rationing to consumer good production.
So what everyone remembers is that Harding (one of the most corrupt presidents, ever) cut income taxes. What they like to forget is that he strengthened tariffs to protect American industries and manufacturing from cheap foreign competition.
Another factor that caused the deflation was that during WWI, unions were able to increase wages for their members and gain power because 4 million men were off fighting WWI. When those guys got back and looked for jobs, industry went through their old tricks of busting up unions and hiring lower-paid scabs. This caused an overall weakening of the buying power of labor unions.
