I live in New Zealand, and we have a healthcare system that’s free to use (YMMV). It’s creaking, but the situation in the US really doesn’t seem to suit anyone, nor even the rich.
Universal healthcare actually means a downgrade in the experience for these people, which is one of the reasons why they don't want it. Yea, they might want to make sure that people don't get sent to the poor house just because they came down with some random disease, but god forbid they have to wait their turn behind some plebe in the doctors office.
But it also means a much higher cost. I know these people are wealthy, but they are getting fleeced. Many (all?) socialised systems also have a private system along side, so the wealthy can avoid the great unwashed.
