I really don't understand why the US doesn't have a grown up healthcare system. Do you just not see how much better healthcare is in the rest of the developed world?
Clarification. US health is great if you are employed, have a good income or are retired and on medicare. If you don't fall into those categories it is pretty tough
Some of these change when you're truly end of life and in the ICU, and otherwise there are brief flashes of doctors actually giving you attention. But for the most part trying to receive healthcare in the US is like squeezing blood from a stone, independent of the soul crushing billing shakedowns.
It's more like you can imagine US healthcare is great if you don't need it, or don't proactively think about what needs to be done. Of course that's a great way for something to go unaddressed and kicked down the road until the next appointment (or ER visit).
I can't speak to other country's failings, but I can say this bogeyman narrative about "government run health care" is utterly fallacious. We already have the equivalent in the form of corporate-bureaucracy-first health care.
