Is as with Dr Johnson and the preacher.
As is typical of theoretical economists, his model makes gross assumptions, including the idea that consumers have no preference, for example, between a US computer and one made in Taiwan, and that the distance goods travel to market is irrelevant.
Preference is as preference is, our trade rules should allow people to express them, exactly what free trade does and restricted trade does not. But there are no computers made in the US these days of course (assembled, maybe, but not really made). Further given container shipping lines distance doesn’t matter in this sense either. We do not buy out iPhones nor logiciels from France because it’s right next door, do we?
