> Is it humane to leave a patient to die in an ambulance when a single-payer nationalized healthcare system is over capacity?

I think painting the inhumanity of that as a consequence of the structure of the healthcare system is disengenuous at best, especially as the implicit solution you're proposing is to artificially lower utilization rate and access. Deflecting patient deaths into "technically not our fault, they didn't try to get help" by exploiting economics is in no small terms extremely inhumane.

The answer to that is that near universally in the world, our labor pool of medical personnel is too small, and almost all of it has to deal with an arbitrary restriction of labor supply. Stupidly, I have felt this many times in America, so trivially it's a problem no matter the structure of the healthcare system. Optimizing towards maximizing the number of nurses, doctors, pharmacists, the whole spread, in a society is underdiscussed but obviously beneficial (for everybody but those who profit off of the labor scarcity)

> I'm not trying to be snarky here, the point is that there is no easy solution and optimizing based on what politicians subjectively consider "humane" isn't going to get us anywhere.

On the contrary, most politicians seem very adamantly against what I'm proposing. I don't know why you think I'm suggesting that we delegate how we determine what's humane to politicans.

is it humane to solve that problem by excluding people based on income? that's what your proposing, as that's how markets solve problems like this: if more people need a product/service than the market can provide prices go up and the poor are excluded. also not trying to be snarky but that's the choice in front of us. part of the problem with free market solutions to healthcare is the feasibility of walking away from a bad deal. in every other space prices are regulated downward by the buyers' ability to either buy something else or do without but there is no doing without emergency care and doing without preventive care is just deferring the cost until it's emergency care at punitive interest.
