globalism, immigration, free trade, etc is/are very good things for the economy.
the only reason i advocate protectionism at the moment is because if all the manufacturing jobs are overseas in countries without a consumer base and our economy tanks those jobs will dissappear because there wont be any consumers to fund them. so not only will we not have jobs but those developing countries wont have them either.
in the long run, on the global stage, competition and free trade benefits everyone. in the short run, certain domestic industries which cant compete on the global stage will suffer. in the long run, the resources and workers that were in those ineffecient industries will move to occupations that are specialized for the location and talent set of region and will maximize production, thereby increasing overall standard of living.
