he is talking about the 90-91 real estate downturn btw. His book is actually very good, easly the best finance related I read in 2007, and he is not as bad as the media make him look like, he did not engineered the housing bubble. he might have made a mistake with too low rates but he had plenty of help from other forces plus its foolish to think 100bps higher fed funds would have prevented the housing boom
