> This is interesting because the USA claims to pursue a maximum capitalistic society
No it doesn't. This is silly.
Drug prices in the US are high for non-generic drugs because patent law gives the patent holder an artificial government-granted monopoly, which is blatantly not "pure" or "maximum capitalistic".
Generic drugs - where the free market does apply - in the US are as cheap or cheaper than in other countries. See [0]:
U.S. prices for brand-name originator drugs were 422 percent of prices in
comparison countries, while U.S. unbranded generics, which we found account for 90
percent of U.S. prescription volume, were on average cheaper at 67 percent of
prices in comparison countries, where on average only 41 percent of prescription
volume is for unbranded generics.
