American care is actually really quite good, but the cost curve is very aggressive, it's something like 2x as much and doesn't cover everyone.
And inverse is true: Canadians believe in some fantastically weird things about the US system.
In my experience as a Canadian living in the US, I was basically shocked at how new, modern and efficient everything was, how service was relatively quick and how knowledgeable the experts were.
The Canadian system 'covers everyone' but it absolutely rations care, you will wait quite a while for non essential services, and in some cases a little bit longer than comfortable for other services as well.
My concern about comparing the various systems, is that I believe a lot of the 'exceptionalism' of the US system bleeds out into the rest of the world and we benefit from that quite a lot.
The challenge is: how do we get the prices down without materially reducing quality of care because even as their gross inefficiencies, it's hard to suck out just the problem costs without affecting the system as a hole - akin to 'losing weight' if you go on a diet, you're going to lose muscle as well as fat.
