I mean, okay, but what if black people live 10 years less than white people in such statistics?

That's still an abysmal thing, as the US would have something like 30% of their population getting clearly worse health and not caring or doing anything about it?

If the difference is down to demographics, surely that's really bad?

Maybe so, but touting Canada's "superiority" over the U.S. would lead to the "obvious solution" of getting rid of black people. If the difference is down to demographics, you want to know that, rather than look at people in country-sized blocs.
