What does the mere existence of 'expensive private clinics' in X countries have to do with the diminishing return on higher priced brain surgeons?

No. I am pointing out that rich people still can and do spend all their money on private healthcare for some tiny increase in countries with public healthcare.

How does that relate to my comment?

It's possible for at least 1 person in any given country to hop on a plane or recruit world experts to come, with enough money, even in Somalia or Afghanistan, which don't have functioning systems of any kind.

I wasn't making any claims to the contrary, if you misread.
