Would you care to back this statement up with numbers? From where I am sitting, free trade has mainly benefited the West with rare exceptions. It has, of course, destroyed countless livelihoods, but so did almost any big economic or technological shift.
Big economic or technological shift won't be as big of a problem if a country gets time to adopt to new technology.
Let's think about this. If tomorrow suddenly Tesla is able to come up with 100% new self driving cars. So what? It still needs to hire the labor to build it and hire the engineers to run the production line and so forth.
Case 1: the borders are closed. Tesla still wants that edge so it will hence take the matters in its own hand and maybe train the engineers to catch up or pay premium salary for engineers who have the skill. Suddenly due to increased wages for this particular kind of engineer society starts to respond to it and gradually trains itself up. In 4-5 years now we have a country which has great technology and self sufficient skills and employed engineers to run it also.
Case 2: the borders are open. Tesla says fudge it. I am going to South Africa, India and China and I can get those engineers. Now suddenly, Tesla is successful and American engineers are caught off guard. American society never got time to respond and retrain. That is what precisely has happened in last 2 decades. The only winner in this case were the corporations.
Whether you like zero hedge or nor but you can't deny the graphs which shows the decline in middle class and rise of extreme wealthy leaving a giant chasm. And we all know the stock market went up and up while the inflation adjust wages never climbed.
