Sounds more like “good old-fashioned” GREED was at work: pumping up a faltering economy, in hopes of making a killing before the feces hit the fan.
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.
