By some measures, the United States is even more deeply in hock than Greece. Greece's debt-to-GDP ratio is 143%. America's is officially 97%. But the $14.3 trillion national debt, stacked up against a $14.7 trillion economy, doesn't tell the whole story. [It] doesn't count the black box of bailouts. We know how much the Federal Reserve doled out in emergency loans: $16.1 trillion between Dec. 1, 2007, and July 21, 2010. We know that because yesterday the Government Accountability Office completed its first-ever audit of the Fed, made possible largely through the persistence of Rep. Ron Paul (R.-Tex.) making that audit, however incomplete, the law. What we don't know is how much of that has been paid back. We have literally injected about $5.3 trillion," said Dr. Paul earlier this month during his questioning of Fed chief Ben Bernanke, "and I don't think we got very much for it. The national debt went up $5.1 trillion." Bernanke did not challenge those figures. Even now, Americans are turning to their credit cards to pay for groceries and gas. According to First Data Corp., the volume of gasoline purchases put on credit cards jumped 39% over the last 12 months. You don't want to be the average American in a default scenario, whenever it arrives. Ray Dalio, the head of Bridgewater Associates, the world's biggest hedge fund, puts that day in "late 2012 or early 2013."
