There really is no such thing as "free" trade any more than there is "free enterprise."
Every country controls imports--except the United States.
Rather than allow U.S. industries, such as textiles and shoes, to be exterminated by subsidized imports, we should demand fair trade, not free trade.
Both Korea and Japan allow very few American-made products to be sold in their countries. Both countries spend very little of their gross national product on defense. Because we provide them with military protection, they can subsidize all their basic industries with funds they would normally spend on military preparedness.
We don't need to worry about coming trade wars; we have already lost much of our basic industries because our leaders are gutless.
