Last summer, Congress passed a law to reform our financial system. It offers the promise that in the future there will be no taxpayer-financed bailouts of investors or creditors. However, after this round of bailouts, the five largest financial institutions are 20 percent larger than they were before the crisis. They control $8.6 trillion in financial assets — the equivalent of nearly 60 percent of gross domestic product. Like it or not, these firms remain too big to fail.
