Large banks and Wall Street firms wrecked our economy. They wiped out pensions and portfolios. Because of their greed, they threw us into a recession, cost us millions of jobs, and squandered American productivity. Yet nobody has paid the price for this wrongdoing. No one has gone to jail. In fact, they remain some of the most profitable businesses in America, doling out hundreds of millions of dollars in executive bonuses. And they pay some of the lowest tax rates in the country.
