I saw this video before but after reader Rick e-mailed it to me I decided to post it. The headline is the interesting part. Greenspan believes the double dip scenario has been off the table for a number of months and that the wealth effect (presumably resulting from quantitative easing) is now kicking in and lifting consumer spending.
Greenspan does not believe he bears any responsibility for the financial crisis and asks critics to "prove" he was wrong. For an alternative take on this, also see my post "Greenspan: Hate Him, Hate Him".
