We have had more economic freedom/less barriers to imports than any large nation on Earth for over 200 years. Wealthy tiny countries like Switzerland and Singapore exempted.
Trump,with his implied trade war against all countries that have a trade surplus with the US, will make us more like Cuba,Venezuela, Bolivia and Brazil.
Closed or less open economies with high tariffs and trade barriers “to protect jobs.”
Much like East Germany had the highest standard of living amongst the Communist Bloc the US,if it joins, will have the highest standard of living amongst the Stupid Bloc of countries because of the inherent skills of American workers.
Gee what a stupid post, where do I begin?

Our exports have hit a barrier that can't be beat - low wages. Everything else you wrote was moot.
