The Netherlands has universal health insurance – and it’s all private

That doesn’t look worrying to me. Think of it: if you ask people wants most important to them, health always is #1. Also, there’s only that much utility you can get from owning ever more clothes, cars, or houses.

Also, the health industry isn’t automated that much, meaning economies of scale don’t work as well there as in other industries.

So, it shouldn’t be strange that, the richer a country gets, the more it (relatively) spends on health care.
