Indeed, I have just realized that the main problem of the US healthcare system is that their inhabitants cannot even imagine that anything better even exists.

Healthcare is much more than being operated or receiving some treatment for a rare condition, both things that are very much researched and done outside the US both privately and with public money. Healthcare is also about allowing people with health problems to live with dignity and allow then to function in society. To care for the weak and not only to restore productivity of a broken cog. Healthcare is about a strong first line of care that prevent conditions to get worse and irreparable. Many countries with a thousand or less of US's GDP can teach a lesson or two on that. In any case, most countries are slowly copying many aspects of US healthcare, I guess it must be indeed be better, or perhaps more profitable.
