It has nothing to do with multi-millionaires, Jeremy. You're flouting your ignorance. If you can get to the U.S., you can get treatment. If you're a pauper, all you have to do is walk into an emergency room. They're required, by law, to treat you. If you're a pauper your problem would be transportation to the U.S., not the medical system, which, knowing nothing about it, you believe to be inefficient. I wish you could talk with some of the Canadians who come down to Florida in the winter for medical care they can't get in a timely fashion from Canada's "free" health care system. Our system has its flaws, but unlike "free" health care they tend not to be deadly.
It's commendable that emergency rooms must treat emergencies, but that really doesn't have much to do with long-term health care and society-wide health outcomes.
This is the 3rd or maybe 4th time that you relate your stories of 'deadly free Canadian health care' on these pages. I assume that you're referring to a few anecdotes you've heard and point out that assigning too much importance to a few anecdotes when making generalizations is problematic at best. And it's often wildly incorrect.
Also, please stop using "free" when describing Canadian health or any other comparable system. Everyone, except you, seems to understand that single payer health coverage is not free, we all pay into our national insurance system one way or the other for the service. Repeatedly, deliberately and erroneously using "free" as a pejorative is dog-whistle bs.
But since you like anecdotes, let me give you one. About a year ago, maybe more, there was a story on the news here (in Canada) about a lady on vacation in the US who sustained a leg injury somewhere, a bad break I think but not certain right now. She had purchased travel insurance through someone reputable, can't remember who, too long ago now. The insurance company estimated that it was cheaper to charter a private jet to fly her home, and pay out cancellation fees on the rest of her trip, to be treated at a Canadian hospital rather than go to a US emergency clinic.
