Le Pen voters are angry for some part, yes. They're the ones with the fewest resources, yes. And you know what? They still get the same health care as anyone else.
One of the consequences of government-provided services, for example, is that it pits native citizens against 'new' and aspiring citizens on the years that everyone decides life is a zero sum game.
Nobody has "everything" figured out, and health care (and paying for it) is a problem everywhere. It's just that comparatively...well, there really is no comparison. In comparison, it is awesome. And I've lived both in the US and in different parts of Europe.
The French voted a 2/3 against Le Pen. The US voted 48:46 against Trump (and got him anyway).
It pits nobody against nobody. It's (almost) universal healthcare, including for non citizens.
Maybe, but Le Pen got a lot more interest than she should have. If the economy was roaring and France was "awesome" would that happen?
