The rest of the world mostly also uses subsidized private healthcare (except for the UK, where healthcare is far worse than in the US).
The US system works well if you can pay the bills. It doesn't have the undercapacity issues the UK has, for example. The unique problem is costs. Controlling costs would mean consumers strongly supporting aggressive action by insurers if they take actions to push costs down. What Americans do is the opposite: they stage protests and demand immediate political retaliation on insurers who try to control costs. Then left wing politicians condemn the insurers, and they fold in the face of public pressure. Medical staff know the public acts this way and so bends insurers over the barrel, knowing people will blame the "capitalists" (who have tiny margins) over the frontline doctors and nurses who are actually taking the money.
In other countries the public doesn't act this way and costs are more reasonable. Sometimes insurance premiums even fall. Switzerland has a two tier system with basic mandatory health insurance that's basically controlled by the government (private firms provide it but there are price controls and they can't refuse customers). And it has supplementary insurance for higher quality care that's almost free market. This year basic premiums went up 5% and supplemental premiums fell 0.9%

Cost control requires private sector discipline without people like Kathy Hochul getting involved, but healthcare even in the USA does not have that.
