Right, I'm not questioning the quality of blue banana or nordic country healthcare. But... are you willing to vouch for the quality of healthcare in Spain or Italy, or some of the eastern EU countries like Romania? Because I lived in Naples and Rome for a combined 5 years and I was not impressed with the quality of healthcare I received compared to what I'm used to in America (for one, doctors don't usually come in with lit cigarettes in america, though I'm told "that's a Naples thing").
But if you have all the money of the world, you could get an extra bit in the US for some health issues. In most cases, it's not worth the cost.
Even then, some Arab sjeiks regularily travel to europe for advanced surgery. So I think that would contradict the first statement.
Eg. The severely sick sultan of Omar last year in Belgium with a 1700 person delegation.
6 covid vaccines have some dependency on Belgium. The Pfizer one was shipped from Belgium to the US.
