It's still going to be prohibitively expensive. Because medical-everything is expensive when you pay 100% out of pocket, even after all the down-the-road factors have taken effect.

$3k for this scope, $11k for that outpatient procedure, $80k for an inpatient procedure - it adds up. Especially when the first thing on the list cleans you out.

As the other response here mentions, even if one has the financial means to just uproot and "move to another country with public healthcare", there's a whole bureaucracy around doing such a thing that makes it hard in the best of circumstances and absolutely grueling if you need medical support for anything resembling a serious and pressing problem.

Even if you're from a country with universal healthcare, but live overseas long enough to be a non-resident of your home country, going back can involve obligatory wait times for rejoining the system. In Canada, for example, i've known this wait time to be something like three months. Imagine managing that while sick and unable to pay for pricey medical assistance.

That kind of money it takes to move a family overseas and then set them up for the length of time needed to find a sustainable job(s) - if I had it, I could also afford healthcare.
