Most Americans pay no attention to the exchange rate of the dollar, unless they take a trip to Europe and gasp at forking over the equivalent of five dollars for a cup of coffee.
Only then do they realize that their paper currency which they once thought was as good as gold, is only worth what foreigners think it's worth. And right now, foreigners have a very low opinion of the dollar.
Since the end of the Clinton administration - or to put it another way, since the beginning of the Bush administration - the dollar has been heading south at an alarming rate.
Against the Euro, a relatively new currency backed by a European economy that is bigger than America's,
the dollar has lost more than a third of its value. The same thing has happened to its value against the British pound.
What's going on here?
Economists can give you a lot of arguments and counter arguments, most of them complex and some a little dodgy, but the simple answer is that America is living beyond its means.
Our government has been doing what the average American has been doing. While American families pile up credit card debt and re-mortgage their homes, the government is piling up national debt and mortgaging our future.
Who is our government borrowing from? Mostly other governments, it seems. Foreign central banks now hold 2.3 trillion dollars (that's $2,300,000,000,000) in American IOUs such as U.S. Treasury bills and bonds. China and Japan are among the biggest creditors. If they decided to sell off a substantial part of this mountain of dollar assets, the dollar would collapse.
Should we care? You bet, as Defense Secretary Donald Rumsfeld would say. The collapse of the dollar would drive American interest rates sky high. Your mortgage would suddenly become unaffordable, your credit card debt all but unpayable. And forget about those foreign trips. Who could afford a ten dollar cup of coffee?
How did our government get to the edge of this cliff? Again, the answer is simple. The Bush administration cut taxes, launched two wars in what it calls the Greater Middle East, and is now bleeding lives and money in an Iraqi insurgency that shows no signs of abating.
