Saying America spends more is pretty weak claim because Americans are fatter, more often shot, face worse natural disasters (hurricanes, earth quakes)... Of course they spend more. There are hundreds of variables why healthcare per capital would be cheaper in Canada from CoL to quality of doctors (the ones that remain are ones who cannot compete in the highly paid US Market), to greater public safety net or social goods in all areas resulting in fewer high cost outcomes (eg, Canadians take more PTO)...
Overall i think the main difference between what you're interested in and what I'm interested in -- that which we're calling "superior" differ.
To me a system is superior if it gives better outcomes to those who pay for the service. VS you seem to be claiming that a better outcome is something like the average across all citizens.
To me this is like saying "We all need food, therefore when we go to the grocery store you will be charged the average bill and given what you absolutely need to not die, but not necessarily what you need to thrive. This is how we keep others from starving..."
For me I want to go to the grocery store and receive the best I can get for my money. It's a just system to receive what you pay for and to not receive what you do not pay for. I do also believe in a separate, external to the government, system of charity to cover cases which are truly unfortunate, but also to keep people accountable for their contributions to their own health when able or
Anyways, it seems you're squarely set your values based opinion, and I am on mine. So there's no longer a reason to discuss further.
