Healthcare is heavily regulated in some countries and less in others. It should be possible to get some comparisons.

I somehow feel that making many humans healthy is fundamentally a really hard problem that gets harder every year because the population ages and expectations rise. It feels to easy of a talking point to put it all on regulation.

Yeah, I know, it's very hard to craft good legislation. In fact, there's this problem of agency: the will to have things be a certain way is not always in the humans, or does not always emanate from the direct needs of the people. Many of the problems of modern capitalism are because there's emergent agency from non-human things, i.e. corporations. In the case of US, agency emerging from the corporate world has purportedly sequestered democracy. But there also agency emerging from frenzied political parties that define themselves as opposition to each other with a salted no-mans-land in the middle. This emerging agency thing is not new; it existed before in other institutions, e.g. organized religion. In any case, the more things there are vying for power, the less power people have to govern themselves in a way that is fair.

With AI, there's a big chance we will at least super-charge non-human agency, and that if we can avoid the AIs themselves developing agency of their own.
