Frontline 's latest documentary focuses on debt. Ten Trillion and Counting "traces the politics behind this mounting debt and investigates what some say is a looming crisis that makes the current financial situation pale in comparison." It aired last night on public television stations around the country. Here's the promo from PBS: The full episode is now available at Frontline's Website, here. And the site includes a set of supplementary analysis and interviews (both in video and transcript form). It may not all contain the depth necessary for understanding the complexities of the debt buildup over the last three decades, but it provides great breadth of Washington voices. Noted economists, members of the Clinton and Bush administrations, and key members of Congress all share their thoughts. For example, New Hampshire Senator, and short-time Commerce Secretary nominee, Judd Gregg on the debt threat: The way I describe it is this: Except for a terrorist getting its hands on a nuclear weapon and exploding it somewhere in the United States, [debt] is the biggest issue we have. We are facing a financial catastrophe of inordinate proportions, because we have on the books obligations which exceed the net worth of the American public. In other words, there is $66 trillion of debt out there, and we don't know how we're going to pay for it. ... The net worth of the United States is $44 trillion, so ... we're essentially bankrupt as a country even though we don't admit to it. And David Walk er , U.S. Comptroller from 1998-2000, on the likelihood of the US's credit bond rating dropping: I absolutely can see the United States losing its AAA credit rating in the future if it doesn't get its own financial house in order. In fact, both Standard & Poor's and Moody's have already issued a shot across the bow, saying that that AAA credit rating is at risk. There are four key factors that led to the current subprime crisis that exist for the federal government's finances: a disconnect between who benefited from policies and practices and who paid the price and suffered the losses; inadequate transparency as to the nature and extent of the real risk; overleverage, over-reliance on credit ratings, and not enough attention on cash flow; and a failure ... of both private-sector and government risk-management oversight mechanisms to act until there was a crisis. So those are four common denominators. There are three big differences. Number one, the American government's financial problem is not as immediate, which is good news; we have time to act. Secondly, it's much bigger. And thirdly, nobody is going to bail out America. We need to solve our own problems, and the time to start is now.
