Most healthcare in the west is subsidized by the US. The US market is far more lucrative, so companies do R&D and make capital from the US. The US also subsidizes in terms of both military and energy almost every western country. Even then, Europe has a higher tax rate and on average is far poorer.
I’m well educated on this subject and worked in this area in the US and spent time in other countries. You have no idea what you’re taking about.
