Sure. College too, right - don't people in most of these other western countries get basically free college, or else really cheap?
But then you also have to take into account lower taxes and housing costs in most of the US compared to most of the richer European countries.
And you also have to take into account the fact that many employers in the US who'd be required to pay $15 per hour are also paying out of pocket for their own healthcare and their kids' college (but are paying less in taxes and for housing).
