Taking Off The Free Trade Blinders

I was recently invited by two Harvard colleagues to make a guest appearance in their course on globalization. "I have to tell you,"? one of them warned me beforehand, "this is a pretty pro-globalization crowd."? In the very first meeting, he had asked the students how many of them preferred free trade to import restrictions; the response was more than 90%. And this was before the students had been instructed in the wonders of comparative advantage!
