Patrick Creadon made I.O.U.S.A. before the current financial crisis, but it’s hard to imagine a more timely film, a documentary that examines the USA’s gargantuan national debt and its drastic implications. It would be a stretch to say the film predicts what’s happened to the financial markets of late, but it certainly offers a damning assessment of one of the major problematic economic philosophies: It’s OK to spend what you don’t have. Creadon presents grim financial fact after fact, reinforced by interviews with financial experts, and yet he still maintains a light tone by following the grassroots campaign, Fiscal Wake-Up Tour, led by David M. Walker, a former comptroller general of the United States and Robert L. Bixby from the Concord Coalition. In the midst of the country’s financial meltdown, I.O.U.S.A. is even more illuminating and enlightening.
