We offshore, but only the pleb stuff. God forbid you want to get a degree in a foreign country, or import medicine, or a doctor. Ask to do any of those and it's protectionism all day long.
I think it's a pendulum. Wait some decades and centuries and that stuff too will get "offshored" elsewhere. And then move between areas, and so on. It used to be that the Arab world was where all the science and math was done. Now it's the bottom of the food chain. It used to be that the Britts were cheaper and faster at building ships, displacing the Dutch's and becoming the world's leader. Now they can't build anything competitively. It used to be that China was the source of most technology, while Europe was stuck in feudal wars. Then they were outpaced by industrializing nations. Now they're mostly manufacturing and develop limited intellectual property. It used to be that Americans studied in Europe to get a proper education. Now the US has the best universities in the world.
I think resistance to offshoring is a natural reflex that's entirely futile.
