Well, Troll, I never thought I would agree with you about anything, but I agree about that one. Yes. I think the Dollar is overvalued. There are disadvantages in having an overvalued currency. It makes it harder to sell products to other people. It leads to being a debtor nation. I do not know what it means to say that a nation is "bankrupt." Bankruptcy is a court procedure, which follows when a person is insolvent i.e. unable to pay its debts. Since the U.S. has never defaulted on its debts, I very much doubt it is insolvent. Brazil, Russia and others have recently defaulted; yet they are somehow still around. The dollar is overvalued, because it is an international currency. People want to hold dollars even if they have no intention of buying from the United States. This makes it harder for the United States to export merchandise. Lots of U.S. businesses would be pleased if the Dollar fell.

If any country "suffers" from an undervalued currency, I would like to know what country that is. When I was in Germany in the 1960's, the Mark was undervalued by about 50%, and the Social Democrats wanted to revalue it. Bankers were against the idea. A devalued currency makes it harder to buy, but easier to sell. Most governments are more interested in selling. Having the Dollar used to measure the price of oil does not give it any "control" over the oil, let alone a "monopoly." The people who control oil are the people who own it.
