Free trade is efficient, in the sense that it increases (or even maximizes) aggregate material welfare. The key words are "aggregate" and "material." As for the first of these words, free trade produces losers as well as gainers. The gainers could compensate the losers, but they are not made to do so. I'm concerned about the losers. In other words, I care about justice (how the pie is distributed) as well as efficiency (how big the pie is). As for the second word, there is more to life than material welfare. Free trade has bad effects on valuable nonmaterial things, such as community, culture, tradition, and family. As a conservative, I care very much about these things.
