Are the outcomes in the US worse? Not that long ago (a couple months ago in fact), I looked at public data comparing cancer survival rates, which put the outcomes in the US at least 10% better than those in the UK. That was additive, such that a 20% survival rate in the UK for a type of cancer is at least a 30% survival rate in the US. The 10%+ better outcome in the US applied to all types of cancers for which I found public data.
I believe the reason for higher US success rates was that the US used more aggressive treatments that the UK would not, since neither does the NHS pay for them nor do their doctors offer them. It is easy to complain about the US system, but the reason that the per capita cost of health care in the US is high could be because the US will try expensive things that the UK’s NHS never would have attempted (since spending exorbitant amounts on aggressive treatments with low chances of success to attain US success rates would drive the per capita cost of medicine to what could be US levels). The high US pricing of those treatments could be further amplified by attempts to take advantage of ignorance. Amplification to take advantage of ignorance was clearly the case in the article author’s case.
I feel like the opposite viewpoint in favor of the US system is not well represented in online discourse, which could very well be because those who were not served well by the UK’s NHS are dead. There are anecdotes about people coming to the US for treatments that they could not receive in the UK or Europe, which is consistent with that.
That said, I have only looked at data for cancer survival rates and not other illnesses, but the cancer data alone contradicts what you wrote. Perhaps reality is in the middle where the UK system is better for routine issues (i.e. you avoid sticker shock), but the US system is better for anything that falls outside of that (i.e. you have a better chance to live). There is evidence both systems have plenty of room for improvement.
