Looking in from the outside this whole reasoning seems to me like some kind of propaganda thats meant to me easily swallowed by americans.
It seems like a deflection that sells the disparity by leveraging american exceptionalism (US medicine is the best) to be swallowed resulting in variying thoughts depending on the disposition of the recipient ranging between "i am glad we are helping those poor people" to "WAAAA why should I pay for them".
But neither of it is really true. The truth as it looks from the outside is that the american people are simply taken for a ride by pretty much all the parts of the healthcare sector.
