Medical care is unaffordable / unsustainable in the high HDI countries and doesn't exist in the low HDI countries.

Would have been interesting to look at the impact on the high HDI countries of mass invasion and demographic replacement. Many of those countries won't be in the "very high" category much longer. That will have the obvious impact on birth rates etc. Ditto long term trends in income inequality, in that population stats meant something when populations were more equal, but the average of oil and water isn't a salad dressing.

Health care is affordable and sustainable in most of the high HDI countries and, in any case, has little to do with life expectancies.

Maybe. Or maybe we're so wealthy and have so few kids that the health care industry is draining off the excess?

In either case, I think it's hard to make such generalizations about a group that includes both the US and countries that have single payer health care.
