It is indisputable that Greenspan understood the problem in plenty of time to address it and prevent the bubble.
mlsoft...While I agree that Greenspan had enough foresight to see the problem coming, I disagree that it is "indesputable" that he never addressed it, or even that he, alone, had the power to prevent it. Such a view would suggest that the Fed Chairmanship is a position of "economic dictator" entirely autonomous with respect to the rest of government, and that, I think you'll agree, is simply not the case.
