An Economy Unaccountable

America's accounting system doesn't balance out and the red is threatening to drown out the black. David M. Walker would know: he used to look over the books.

Walker was comptroller general of the United States and CEO of the Government Accountability Office from 1998 to 2008. In that time he reported on the growing fiscal imbalance the country was facing, but saw little action from our leaders to address the issue. Walker was prominently featured in the acclaimed documentary "I.O.U.S.A."

Now, as president of the Peter G. Peterson Foundation, Walker is taking an active role pushing for the change of what he says is a broken system that is "headed for a cliff."
