"No Veto, New Tone in Washington" Bush does deserve a good chunk of the blame, but Greenspan, Clinton, and Rubin did get the ball rolling.
And even if it isn't true, and Greenspan manages to keep all the balls in the air, it's a wonderful rant.
Greenspan has stepped into the shadows making sure he gets none of the blame. He's already stated that he's powerless to help the economy -- the same man who soaked up all the credit when the economy was doing well.
