Amen. When it becomes cheaper to move goods than people, capital goes where the people are, not vice versa. The container ship and the internet have made the oceans unimportant as trade barriers.

But what does the world look like if Asian, African, and South American workers get G7 type labor regimes? Won't trade revert to it's original purpose, the exchange of raw goods packaged as final goods (e.g., rainfall as cloth, sunshine as wine). Take away cheap labor, how else does comparative advantage arise?

Your argument is moralistic not protectionist. You are concerned that we American consumers are complicit in the exploitation of foreign labor. I agree that American tariffs would result in better working conditions abroad, not because the producers would want us to reduce the tariffs, but because they will focus on local consumption, adopting a Fordist labor model in which workers can afford to buy what they make. Conditions for foreign workers would improve, but much trade would shrink, and prices here would soar.

Is our price-addicted electorate ready for the change? The fools who voted for Trump will find out that protectionism isn't to their liking, because it will help foreign workers more than US workers. Whom will they blame?
