The total potential federal government support could reach up to $23.7 trillion," says Neil Barofsky, the special inspector general for the Troubled Asset Relief Program, in a report released today on the government's efforts to fix the financial system. "The potential financial commitment the American taxpayers could be responsible for is of a size and scope that isn't even imaginable," said Rep. Darrell Issa, R-Calif., ranking member on the House Oversight and Government Reform Committee. "If you spent a million dollars a day going back to the birth of Christ, that wouldn't even come close to just $1 trillion -- $23.7 trillion is a staggering figure." The government has about 50 different programs to fight the current recession, including programs to bail out ailing banks and automakers, boost lending and beat back the housing crisis. So far they've cost taxpayers around $4 trillion. But Barofsky says if each federal agency spent the maximum potential amount involved in these initiatives, taxpayers could be on the hook for trillions more. The watchdog also warned today that hundreds of billions of taxpayer dollars could be lost if the government does not increase the transparency of the TARP program, which he says has grown to an unprecedented scope and scale. Requiring TARP recipients to report on how government funds are used is among the recommendations urged by Barofsky. He also wants the department to report on the values of its TARP portfolio so taxpayers know about the value of their investments.
