Walter Williams explains trade deficits. The punchline:

Some politicians gripe about all the U.S. debt held by foreigners [as a result of our trade deficit -- kb]. Only a politician can have that kind of audacity. Guess who's creating the debt instruments that foreigners hold? If you said it's our profligate Congress, go to the head of the class. If foreigners didn't purchase so much of our debt, we'd be worse off in terms of higher inflation and interest rates. What about the possibility of foreigners dumping our debt? Foreigners aren't stupid. Dumping large amounts of Treasury bonds would drive down their value. Foreigners as well as we would take a hit.

The fact that foreigners are willing to exchange massive amounts of goods in exchange for slips of paper in the forms of currency, stocks and bonds should be a source of pride. It means America, with its wealth, rule of law and the sanctity of contracts, inspires foreigners to hold large amounts of their wealth in U.S. obligations. Their willingness to do so means something else: Trade increases competition. Ultimately it's competition, many producers competing for his dollar, that truly protects the consumer. What protects producers, at the expense of consumers, are restrictions on competition. The quest to restrict competition is what lies at the heart of the trade deficit demagoguery. When's the last time you heard a consumer complaining about his buying more from a Chinese or Japanese producer than that producer buys from him?
