This moment requires some hard rethinking. How well does free trade really fit with the other things we want in modern societies? I was just re-reading work on globalization from an economist colleague, Dani Rodrik, at Harvard. And he says you cannot have all three of the following things simultaneously: democracy, national sovereignty and free trade. For example, you cannot have international trade without some international rules, and those rules have to be enforced by somebody with international power. So if you want a globally integrated world, you have to give up some sovereignty.
