nobody wants to hear it. the cause of the 08 financial crisis tracks directly back to congressional republicans (gramm) and democrat executives (clinton) unwinding sensible regulation from the great depression on the delusional belief that we'd gotten better at "understanding" and quantifying "risk".
Absolutely agree with what you are both saying, in that DC enabled Wall St by foolishly deregulating investment banking and banks.
Of course, that does not absolve Wall Street of blame for managing risk poorly, for fraudulent behavior, for negligence, and for short-term risk taking over long-term growth.
