Earlier quoted context omitted.
There is a reason that most of the best hospitals in the world are American Uh, do you have anything to back that up, apart from the standard assumption that "US is #1 at everything!"? And even if you had 10/10 top hospitals globally, overall average quality is a better metric than handpicked best-of-class examples.
If you have an especially difficult medical problem or you have the money and want the best possible care, your hospital of best choice is probably American. If you're talking about average medical conditions and the average outcomes... maybe not, but those statistics are usually about the medical systems as a whole which is much more difficult to compare in a country without universal health care.
Again, do you have anything to back this up? My question isn't about there not being good hospitals in the US, but rather the assumption that the best ones in the world must be American.
Also, I think you definitely mean "and" rather than "or" in that sentence. If you have a difficult medical problem and no money, then your best hospital is going to be one that will treat you rather than turn you away for having no money.
