Everywhere outside the "developed world". By the numbers, the global norm is free-market healthcare, where the patient directly pays the doctor.

And yet, even that delivers a cost structure that is infinitely preferable to our circus over here.

I personally favour socialised medicine. The point is that whichever extreme you go to, it's going to be better than the morbidly obese, hyperinflated, worst-of-all-worlds catastrophe in the US.
