I didn't really find anything helpful, but there is a story that's going around conservative blogs that it was the liberals' obsession with extending credit to minorities that ultimately caused the crisis.

There's a lot of things wrong with that story. This American Life just did a segment on it. They point out that the problem really originates elsewhere, on Wall Street, and that both conservatives and liberals share the blame here. Listen to the second segment of this episode:

It's arguable that the mere existence of the Fed or FDIC does contribute to overconfidence, especially when it's pursuing a low interest rate policy.

Only to banks not to private institutions which were the leaders of these issues such as AIG, etc.

that didn't help.
