The way I see it, European countries have a kind of nation-wide health insurance, vs individual insurance here. We have a nation-wide student loan, versus individual student loans. That helps controlling the costs and profits, and helps making sure that everybody who needs care or education can get it.
But whether it is related or not, America is more daring, more exciting, and there are more opportunities when you have the right cards to do something. But if you had a bad hand to start with, then you're royally screwed.
Put simply, it's better to be born poor in Europe than in the US, and better to be born rich in the US than in Europe.
