I like how you mentioned there's no purely capitalistic healthcare system in the world, even in the U.S. there is massive government involvement in Health Care (120 millions Americans are on medicare/medicaid for instance which is twice the population of the UK if i'm not mistaken), additionally Switzerland which seems to have the best healthcare in the world also has very strict government regulation. When it comes to drug pricing there's another caveat which is a lot of the incredible R&D breakthroughs aren't even done in the states but rather they are done by British and Canadian companies that then markup the prices in the US because it's the only place they can charge people lots of $ (and even in the US they have to sell at a reduced cost to the third of the population that is on medicare/medicaid as stated earlier). So in short the U.S. healthcare system isn't entirely capitalist and the pharmaceutical companies in countries with national health insurance are very capitalist when it comes to selling their drugs in the U.S...basically nothing is what it seems.
