The bankers did not cause it but they ran with it. The politicians and probably Soros triggered it to destroy the Bush Presidency and elect Hussein. The scope of the looting was magnified by the fact that all the government finance men and "economists" were out of one company, Goldman-Sachs.
It was/is a frantic looting of the shareholders and then the Treasury, by the bankers and the politicians and the bureaucrats- the "regulators."
Capitalism has, indeed failed, because it made the society rich enough that it could afford to support its intellectuals in idleness with time to think up great Utopian schemes and support great masses of "poor" to vote for all their schemes.
Sorry, but I can’t see Mr. Bush as a “victim” in this mess.
In 2002 (not sure of exact date)he told a cheering Congress,and an approving Public, he wanted to extend the benefits of home ownership to people previously considered “less qualified”. (No, I can’t cite, as I’m doing this from aging memory.)
His “benefit” was not money, but acclaim : something I suspect he wanted badly (typical pol in that respect.)
