a) The American Healthcare system is currently design by Democrat policies that passed without any Republican votes whatsoever. So yes of course it’s a failure it tries to combine socialism with capitalism and succeeds at neither.
b) Then vast majority of Brits may not complain about the NHS. Then again the vast majority of Brits are fine with limiting Healthcare to elderly while the Torah is decidedly not fine with it. They are also fine with encouraging certain children not to be born, again the Torah is not really fine with that. In other words much of the rationing that takes place is aimed at populations we value while they do not.
c) In addition if you get a rare condition of disease your treatment options are vastly more limited in Britian then the USA. As someone who suffered from a rare neurological condition, I had firsthand experience with this. As my doctors basically said straight out in Socialist countries my treatments would not have been available.
So yes for vast majority the NHS works, then again the vast majority do not really get terribly sick do they?
d) Yes you were referring to a group of tiny countries compared to the USA. As I noted it is simply intellectually dishonest to compare single state countries to 50 state countries.
e Yes those countries afford a safety net. So does the USA the programs I mentioned combine to form They were designed and implemented to ensure children do not starve. people get medical care, the elderly are taken care of.
Is your contention that those programs have failed?
