So, in the end, you're accepting that regulation is not the determining factor then.
Not even sure what exactly you think the proportion of foreign-born medical staff is in Europe. As far as I can find, the maximum is ~30% in the UK, while in Germany is 7%. But either way, to think that this is somehow the reason why Americans pay way more than anyone else for basic stuff like insulin and medical bills is ridiculous in my eyes.
Even if what you say is true for Western Europe, there are other countries (pretty much all) with highly-regulated healthcare and they all pay less than the US. But I'm sure there's some niche reason for why that would never work in the US.
