There is nothing worse than people who had legitimate power screwing with things after they're out of office.
That is why former presidents aren't supposed to get involved in politics and why they mostly focus on charity type stuff (ie Bush Sr. and Clinton during Tsunami crisis, etc).
Greenspan is the cause of the fricken economic problems now and all he's going to do by commenting, especially recessionary talk, is going to drag our markets down.
I'll bet he has a nice big short on broad based index ETFs.
