The problem with the U.S system is everyone has their hand out for money. In America, Money is considered the universal yardstick for success and universally effective solution to all problems. The health care industry grew 20% last year? Fantastic!

It's a perfect example of the civilizational collapse process that Joseph Tainter, a professor of archeology, wrote about in his book "Collapse of Complex Societies"[1]. A society will get some sort of civilizational process that works to create wealth in their society. The civilization will continue to increase complexity to exploit this process and when the process starts returning negative marginal returns the collapse process begins because the whole civilization can't switch into reverse. This happened to the Romans with their conquer and receive tribute process for example. It eventually started yielding negative returns and they couldn't reverse course. The inertia was just too great.

Well, its politically impossible now, but people opposed to it are dying every day.

Same sex marriage, marijuana decriminalization/legalization, etc all took time. This'll take time as well. I just wish people didn't have to suffer and die because of their fellow citizens' shortsightedness.

"Progress occurs one funeral at a time."

You need a politically strong somewhat lefty government to ram it through against the vested interests who are rich from the present system. Single payer was opposed similarly in the UK but we had a landslide left wing government after WW2 who got it done. A shift in the US towards say Sanders could do it but it doesn't look like that's happening this time around.

There's hundreds of factors affecting the efficiency of a singe payer system in the US compared to other countries, including population size, illegal immigration, crime rates, etc.

Solutions for one country may not work for another
