Vapaa kauppa ei ole aina ihan täysin vapaata:

But, of late, a troubling twist in the game has become more common, as countries use free-trade agreements to rewrite the laws of their trading partners. And the country that is doing this most aggressively is the United States.

Our recent free-trade agreement with South Korea is a good example. Most of the deal is concerned with lowering tariffs, opening markets to competition, and the like, but an important chunk has nothing to do with free trade at all. Instead, it requires South Korea to rewrite its rules on intellectual property, or I.P.—the rules that deal with patents, copyright, and so on. South Korea will now have to adopt the U.S. and E.U. definition of copyright—extending it to seventy years after the death of the author. South Korea will also have to change its rules on patents, and may have to change its national-health-care policy of reimbursing patients only for certain drugs.
