also take a look at the health care system,
only recently US manufacturing industry is starting to come around to some kind of national health care system.. because theyre being undermined by the current inefficient and expensive US system. But its employer compensated (in part) and makes productions costs when competing with those that have a national healthcare system..

GM makes the same car in Detroit and Windsor across the border in Canada. In Windsor the production is something like a $1000 cheaper because of the national healthcare system.
