There's a misconception in the US that foreigners come to the US for healthcare and that somehow vindicates our shitty insurance/payment fuckuppery-industrial complex. In fact, (1) most of those foreigners come from the Third World, not W. Europe or Canada, and (2) to the extent that it is true, they come for specific doctors with global reputations, and would go to whatever countries those doctors lived in (and some are in the US, some are not).
