Too big to save?

When enough financial institutions that are "too big to fail" totter at the same time, the government cannot save them all.

What worries me is the possibility that the federal government and Federal Reserve will sink $2 trillion, $3 trillion, $4 trillion into stabilizing the financial system and then simply run out of real money (as opposed to inflated money), leaving them powerless to intervene further and thus bringing on a truly catastrophic crash. The taxing ability of the federal government—its ability to back up its financial commitments with revenue taxed from Americans—is large, but it is not infinite.
