Wall Street cooked up the idea of bundling shady mortgages and then selling them as mortgage backed securities and a whole lot of these CEO's you're championing here didn't hesitate to risk their investor and depositor funds on these glorified Ponzi schemes.
I do not disagree that the Clintons started the ball rolling, but it was greedy and short-sighted leadership on the Street that made the situation worse.
Before you let congress off the hook, you need to read up on Glass-Steagall Act and Gramm-Leach-Bliley (GLB) Act.
Prior to GLB, banks could not sell mortgages backed securities.
