Comparative advantage

I found this brilliant article, which explains why famous intellectuals commenting on international trade baulk at basic concepts, in this case comparative advantage.

I particularly enjoyed the author’s first suggestion for what can be done:

(i) Take ignorance seriously: I am convinced that many economists, when they try to argue in favor of free trade, make the mistake of overestimating both their opponents and their audience. They cannot believe that famous intellectuals who write and speak often about world trade could be entirely ignorant of the most basic ideas. But they are — and so are their readers. This makes the task of explaining the benefits of trade harder — but it also means that it is remarkably easy to make fools of your opponents, catching them in elementary errors of logic and fact. This is playing dirty, and I advocate it strongly.
