The US also has a large incompetent population, compared to Europe. Europe only recently got a huge surge of under-skilled refugees, and this should weigh down on the system (some countries like Italy/Spain are already near bankruptcy).

The US also spends a lot on its military, which is part of the social safety net. Europe ignored military for other expenses and is now paying heavily for it.

That being said, the US does not make good use of its resources. But it's a much harder problem that you'd expect.
