I've always wondered to what extent the high cost of health care in the US is subsidizing universal health care in other countries. If it actually costs millions of dollars to create and test a single medication, but that medication is cheap in other countries and expensive in the US, universal health care in the US may drive up the actual cost everywhere else.
Economically speaking I am ok with that. Easier access to a product universally will lower its cost per consumption on average even if that average is a price spike for certain locales. This is a way of saying the outcome benefitting the most people isn't necessarily universally beneficial.
