Well, I guess their money can collapse right along with ours.
Yes, but when everybody’s money collapses, the U.S. government (taxpayer) is still stuck with its promises as an “insurer” of that money.
Will the U.S. tell everybody in the world that deposited into FDIC-insured accounts “too bad, the global banking system is hosed,” or will it frantically try to print even more money and find even more ways to mortgage our future?
