According to Bloomberg:
U.S. taxpayers may be on the hook for as much as $23.7 trillion to bolster the economy and bail out financial companies, said Neil Barofsky, special inspector general for the Treasury’s Troubled Asset Relief Program.
Hmm. That's more than the total value of all U.S. housing. That's almost twice the GDP of the U.S. I hope Neil's figures are off.
