The Fed's zero-interest-rate policy is also still giving a gigantic subsidy to banks by allowing them to borrow money from the government for nothing and then lend it back to the government at a ~3% interest rate. The spread on this trade continues to produce massive Wall Street profits, and, with them, enormous bonuses--without any of the risk that is normally supposed to accompany such profitability.
