>> You used the bandwagon approach and a hasty generalization as substitutes for argument <<
Nothing “hasty” at all about my approach or my argument. The case for free trade been studied, analyzed, and empirically tested time and again since the days of Adam Smith, that is, over the past 233 years. The scientific literature on the matter is so vast that one truly could spend a lifetime reading it.
Moreover, if Adam Smith, Milton Friedman and Tom Sowell are all on the free trade “bandwagon,” then that’s where I want also to be. I’m proud and happy to be in such company.
In any event, Smith, Friedman, Sowell and literally thousands of other economists have done all of the analysis and all of the argumentation that anyone could ever wish for. No propostion in philosophy or science has ever been more thouroughly vetted than has the notion of comparative advantage (or “gains from trade”), and this proposition has stood the test of time — both logically and empirically — at least since 1776.
In other words, further argumentation or explanation is genuinely unnecessary.
