But earning more means paying more taxes. If the tax rates are comparable, then your argument entails that the US government gets even more tax revenue than other countries per capita, so it makes even less sense that it then presumably spends those tax dollars on things that are not related to healthcare, whereas countries like Canada and UK do consider healthcare one of their priorities in their budgets, while still maintaining things like military operations and space programs.
