USA is terrible at healthcare for those that don't have a safety net but many countries, such as UK, are terrible for the middle income/stable job types, because you don't even have options (unless you pay a fortune) without months on end.
It's just a different type of scam.
There's definitely better implementations.
Doctor: € 25 (Of which you get at least half back)
Standard lab test: € 20 (Real cost is € 50 or something)
Still pretty far from € 400.
US healthcare costs are too high in the US because of the broken insurance system. I don't think it needs to become a public system like Europe. I don't see anything inherently wrong with private insurance. But the system needs a reset, back to normal prices.
One of the reason costs are too high is because hospitals, doctors, labs, know that insurance will haggle down so they just overcharge a lot. That's how you end up with an ER band-aid costing $ 500.
The American system brutalizes poor people because it's cruel and stupid. It doesn't save you a dime on your taxes.
