The care is mediocre according to WHO. Certainly substandard by the standard set by the other industrialized countries. (anecdotes have no bearing here, only what is true on average) We can not separate health insurance from health care. Only by paying a large amount spread out over a lifetime can anyone, other than the very wealthy of course, outside the U.S. Welfare System afford U.S. health care. Without insurance, we are all just one major health calamity away from bankruptcy. If there is a Hell, this is it.
I'm pretty sure the Rwandan genocide was worse but I know what you mean, even then over time the US numbers of citizens dying horribly have been millions for sure. A close friend of mine with a young family, relatively well off but had just spent everything on a house, had his chemo interrupted significantly due to his insurance thinking they had found a loophole. He died in 2008 just a year after diagnosis. He may have died anyway but one can be certain, the gap in treatment and months of anger did not help.
Knowing better now, I'd have said get your ass to Mexico or Colombia and just pay cash for the treatment but he was idealistic. I recall too well when he rang me in Ireland after coming home from his congressman who said he could do nothing however 'he would include him in his prayers'.. FFS.
