REALISM

If China does decide to back the yuan with gold and no longer use the U.S. dollar in international trade, it will have devastating effects on the U.S. economy.  Demand for the U.S. dollar and U.S. debt would drop like a rock, and prices on the things that we buy every day would soar.  At that point you could forget about cheap gasoline or cheap Chinese imports.  Our entire way of life depends on the U.S. dollar being the primary reserve currency of the world and being able to import things very inexpensively.  If the rest of the world (led by China) starts to reject the U.S. dollar, it would result in a massive tsunami of currency coming back to our shores and a very painful adjustment in our standard of living.  Today, most U.S. currency is actually used outside of the United States.  If someday that changes and we are no longer able to export our inflation that is going to mean big trouble for us.
