> Are the ultimate free market advocates on Wall Street secretly non-believers in free markets?
What makes you think that the Wall Street folks are free market advocates? (Goldman Sachs, in particular, is a huge believer in govt intervention, perhaps because almost all of the folks in govt making such decisions have Goldman ties.)
In other news, big biz isn't a free market advocate either. GE is lobbying for govt mandates for its products. Walmart is lobbying to increase the health insurance costs of its competitors.
If you don't want big biz running something via govt, you can't let govt run said something. Regulatory capture is how things work.
