“Country A, though it spends twice per capita on health, has a lower life expectancy than Country B.”
This is an unconvincing statistic without further context.
What is counted in the money spent on health? Is it treatment? Or prevention? Or both, plus others?
I suspect that for the majority of largely Western ailments and diseases, the paramount factor that determines healthfulness is not the amount of money you spend when you get sick.
Instead, it’s the things that don’t cost much money – changes to diet and lifestyle.
There is a clear difference between treatment and prevention.
It is much more difficult to convince somebody to part with money to prevent something than it is to cure it.
The latter is a real problem that needs fixing. The former is merely the thought bubble of a distant possibility.
