This just means American consumers end up subsidizing health care R&D costs for the rest of the globe — purely because our government prevents us from collectively bargaining the way pretty much every other country does.
The people coming to the US for the “best quality” are generally going to doctors / surgeons in private practice, most of whom do not take insurance and can see you immediately. There is an almost entirely separate (and much higher quality) medical system available to those who can afford it. The system the rest of us belong to ranks right behind Morocco and Costa Rica in terms of outcomes (not joking — this is according to the WHO). We come in dead last among “first world” countries.
