Check out the above video, one of the series, of Michael Lewis in conversation with Jacob Weisberg of the Slate Group. It's a quickie but a goodie. Lewis covers a lot of ground. The young guns of Wall Street shouldn't have been getting paid $2 million! Credit default swaps (a) shouldn't have been invented — "innovation" in finance is not necessarily a good thing — and (b) were bound to lead to people betting against the securities, mainy home mortgages, they were based on.
But things really get interesting when Lewis starts sounding exactly like L. Randall Wray, an increasingly prominent economist from the University of Missouri, Kansas City, and a proponent of an increasingly popular new school of economics thinking called "Modern Monetary Theory" (some call it Neo-Chartalism). Wray also says the big banks need to be broken up. I've embedded a video below in which he discusses this idea. He's not exactly Michael Lewis. But the message is quite similar.
