Neither comment was directed at you and I’m sorry if they read that way - M4A (specifically) discussions usually center on people who live in a big city and are solving only for that. I’ve also agreed in several comments that single payer is a likely component of the right solution, but that current proposals are woefully insufficient, to the point of not even being solutions. I’m all in for incremental improvements (the ACA was certainly one), but not if it just trades my pain point for creating five new ones for you.

The difference between HK and the US starts at the fact that one is 1100km^2, and the other is 9.8 million km^2. Solutions that work well in what’s essentially a really dense city don’t, necessarily, work across a massive country with a distributed, diverse population that faces very different, area-specific challenges.

I’ll add, apropos of nothing, that the fastest way to make healthcare in this country better is to fix education costs. If we dramatically increase the number of people in med school/nursing school, and simultaneously dramatically decrease what they owe upon graduation, you will see far more high quality providers enter the system who will be far more able to practice in places that really need them.
