The banking systems problems are a cultural issue. The financial markets should have a stewardship culture, where they don't pursue high return products. It's not a regulatory issue, noone needs to go to jail.
I liked the part when the banker they had on said '...large banks need more stringent separation between depositors and investors to allow bailouts for consumer runs while keeping investment markets free to fail" and Spitzer said "that's not really the role of regulation", and "i'm glad we didn't catch JP Morgan losing money on a hedge"
