Watching a little 4-year-old die of cancer because she was born to poor parents is not the same thing as not exercising as much as you should.
I work in healthcare. I assure you they are not. And when people don't pay, all they do is just jack up the prices for those who can. So society bears the cost one way or the other. The difference is, when people have insurance, they get preventive care more- like $10/mo blood pressure medicine. That's much cheaper than someone not getting that care and ending up in the ER at 3 am with chest pain requiring emergency cardiac catheterization, kidney failure requiring a lifetime of dialysis, and going blind for the rest of their life, all from uncontrolled blood pressure because they couldn't afford annual checkups.
Countries like S. Korea and Germany did much better with COVID than countries like us. Why?

Universal Healthcare systems have improved the public health everywhere they have been adapted. The latest unqualified success has been Thailand. They still have top quality healthcare, and are a top medical tourism destination from many countries, including the US. However, since the introduction of a UHS safety net, their public health has improved dramatically by almost every measure. But surprisingly and unexpectedly, their rate of extreme poverty also dropped. Why? It turns out that the extreme poverty in their country was almost all due to unexpected catastrophic illness in an uninsured family member, with the entire rest of the family going broke trying to pay for it, kids dropping out of school and college to work to pay for it, etc... The result of lifting that burden has been that their economy has also started growing faster. Double bonus!

I don't see the problem with a hybrid private/public healthcare system here as well, like the one in Thailand, or the one we already have here for public education. If you have the money, you can still send your kids to the most elite private college-prep Ivy-League-feeding boarding schools. But if you don't, we still have the public school system as a backup safety net system to make sure our populace has some basic education. We all benefit (and don't tell me about charter schools- those are still paid for by public funds).
