You'd treat America like just another country and wouldn't put your People first. You'd invest equally in foreigners, even though foreign countries would favour themselves, putting your country at a decided disadvantage.
I can see you shrugging your shoulders at companies shipping jobs overseas and saying, "Well, they work harder, they deserve the jobs." And forcing social Darwinism on a decidedly non-Darwinistic situation. It's impossible for Americans to compete because it costs more to live in America than it does to live in China. If I worked for the wage they work for, the same hours they work, I would not make enough to live even at lower standards than they live.
