How many trillions of U.S. dollars in debt can this country pile up before the currency is devalued. I was listening to local talk radio last evening, and an uneducated guy called in. His grammar was awful, but he said he reads and is learning more every day. He opined that "they" (the "illuminati"?) want to destroy the U.S. dollar so they can establish a North American/Latin American currency similar to the Euro. I'm not so sure that the guy isn't on to something!
