Ah. I see. You are going back to old Adam Smith. Let places/people that can make things more efficiently, do them. Example: Don't give subsidies to car companies in countries that aren't good at making cars, it is inefficient. Better to focus on what you are good at. There are exceptions: National Security. See Energy, Semi-conductors. or To protect an industry while it grows, gets up to speed. Japan didn't become industrial power house out of nothing, they were very protectionist. Now they are dominant, but they aren't dominant because they let anybody at all come in and compete. They subsidized and protected their industry until they could stand on their own.
