Earlier quoted context omitted.
The Japanese system is not a single payer healthcare system and in terms of outcomes vs. cost is one of the best in the world, so I am not so sure that single-payer is the most reasonable solution. Particularly in the US where voters are averse to giving up their private insurance. Japanese system does have a public option and much tighter price controls, which we are missing here.
What the US is missing to achieve that is japanese culture. It can't work the same or even similar.
Obviously we shouldn’t just exactly copy the system of other countries, but it’s equally shortsighted to not learn take away anything from other existing systems. The possibility for universal coverage and higher cost efficiency without the need for single payer I think is a valid thing to take away from those examples.
