I find such figures difficult to interpret, though (like here: https://www.healthsystemtracker.org/chart-collection/health-...)

It could be that richer countries simply have more money to spend on health care, so why wouldn't they spend it.

On the other hand many health outcomes may also depend on wealth - for example over-consumption leading to obesity, which might affect health more than spending on health care can compensate.

In that example, a rich country could spend more money on health care and still have worse average health than poorer countries.

Not saying that is exactly what is going on, just that it makes sense to be careful with judging.
