These banking Goliaths have powerful constituencies and substantial political power. Keep in mind, the Obama campaign received over $10 million in contributions from Wall Street, the largest contributors by far.
Nobel prize winning economist Joseph Stiglitz sums it up like this:
"The fact of the matter is, the banks are in very bad shape. The U.S. government has poured in hundreds of billions of dollars to very little effect. It is very clear that the banks have failed.
“American citizens have become majority owners in a very large number of the major banks. But they have no control. Any system where there is a separation of ownership and control is a recipe for disaster.”
Economist James Galbraith says the same thing in an interview on Democracy Now with Amy Goodman:
"I think it’s fair to conclude that the large banks, which the Treasury is trying very hard to protect, cannot in fact be protected, that they are in fact insolvent.”
