Reddit mentions of Affordable Excellence: The Singapore Health System

To some degree, but largely they still pass on healthcare costs to everyone very efficiently.

It's been a while since I read up on it, but essentially the entire system revolves around a very robust HSA system where you pay for everything in cash, but either you or the government contributes to a private account to pay for it (based on income, need, etc). Then the government can put up public hospitals, but they still largely have to compete on price with private institutions as well (since people are ultimately paying with their own money).

Ultimately I feel like it would be a lot easier to implement in the US. You can start small. It preserves consumer choice. It can be implemented at a state level. And it will help combat costs (by making prices more important).

Singapore. And according to what I've read it performs very well.
