That it’s actually usable? Great healthcare is pointless if you cannot afford to go to the doctor.

Sure, but what standard of high school degree?

And yet Americans seem to survive more often with a healthcare they supposedly do not use than Italians and Frenchmen with a healthcare they use.

> Sure, but what standard of high school degree?

Surely you aren't implying that the standards of an American HS degree are so low that the education that that huge percentage of the population with a middle school degree or lower is receiving is comparable to it?

Well. Yes? Anecdotally at least my experience with degrees given outside my home country is that they often appear to get given for attendance, not attainment. A high school degree means anything from “can do higher order math blindfolded” to “doesn’t know how to do addition”.

>> France and Italy have top-tier universal healthcare

>According to what parameters? For what it's worth both seem to rank lower than the US according to the OECD.[2]

That would be surprising, since the US doesn't have universal health care.
