In a major shift from his days as head of the Federal Reserve, even Alan Greenspan said last week that it's time to break up those banks and brokerages that are "too big to fail." The financial giants are handing out billions in bonuses again, and they've spent $224 million lobbying against efforts to regulate excessive risk. But their critics insist they're the ones who brought the global financial system to the brink of collapse. Ninety-nine smaller banks have failed during this year alone. Citibank and Bank of America aren't doing so well. If the financial system isn't repaired, will it be taxpayer-bailout time all over again?
