Who's to blame for the biggest financial catastrophe of our time? There are plenty of culprits, but one candidate for lead perp is former Sen. Phil Gramm. Eight years ago, as part of a decades-long anti-regulatory crusade, Gramm pulled a sly legislative maneuver that greased the way to the multibillion-dollar subprime meltdown. Yet has Gramm been banished from the corridors of power? Reviled as the villain who bankrupted Middle America? Hardly. Now a well-paid executive at a Swiss bank, Gramm cochairs Sen. John McCain's presidential campaign and advises the Republican candidate on economic matters. He's been mentioned as a possible Treasury secretary should McCain win. That's right: A guy who helped screw up the global financial system could end up in charge of US economic policy. Talk about a market failure.
