Many people—many economists—usually devoted to the free market stop short at money. Money, they insist, is different; it must be supplied by government and regulated by government. They never think of state control of money as interference in the free market; a free market in money is unthinkable to them. Governments must mint coins, issue paper, define “legal tender,” create central banks, pump money in and out, “stabilize the price level,” etc.

My friends, there is good news and bad news.
The good news is that the full faith and credit
of the FDIC and the U.S. government stands
behind your money in the bank.
But the bad news is that you,
my fellow taxpayers,
stand behind the U.S. government.
