All this whilst paying less than half the amount the US does per capita.
This is the killer point, right here. How can the US claim to boast an amazing healthcare system when it costs twice as much for what are, if we are being honest, mediocre outcomes? Life expectancy and quality of life lag behind Western Europe and Japan, largely because we would rather let a small share of the population have access to the best treatment on Earth (no matter the cost) while simultaneously leaving a lot of people with inadequate access or no access at all. (And by "access" I also mean "affordability" since whether or not someone can pay for their care is always a factor in the US.)
