From Bob Ladd, Edinburgh, UK
Lawton gives a clear worked example of why free trade is win-win. But the conclusion is based on the premise that the players in the game are national states and that the measure of comparative advantage is economic growth. If instead we treat humanity as the only player and define economic growth as the accelerating extraction of wealth from a finite planet, then it is reasonable to believe that, in the long run, we and our descendants are in a zero-sum game after all.
