the biggest problem is not even that. our countries are rich not because we are actually productive economies but because we are safe countries for billionaire oligarchs to sit their money in. toronto has fewer millionaires than chicago when you subtract home equity from net worth. vancouver's millionaire rate is 1/10th that of torontos, basically all the wealth there is in housing and will evaporate if/when the housing bubble pops. if the usa tried to impose controls on the oligarchs in order to bring back manufacturing and other productive sectors, they would just flee to tax havens and collapse the financial system. its a very grim situation, though the usa (and canada) is in the best position in the world in terms of location, land and resources so if americans are willing to suffer tremendously in the short term you could come back with a vengeance within a few decades
