So, despite the site having “populist” one of the new words for communist, right there in the name I went and waded through it. He’s just saying he doesn’t like free trade.
Actually, if you Google for the in depth analysis called “The Unraveling of Economics” (cited in the essay) there you will find the detailed theoretical model. I’ll see if I can post that here tomorrow.
Just to clarify. It’s not that I don’t “like” free trade. I believe it is defective economic theory (i.e. Ricardo’s theory of comparative advantage is logically flawed). Instead of making a country rich, it will cause economic harm.
