Health insurance's issue is probably how it induces pure waste everywhere as everyone has to play this dance of ever escalating paperwork which consumes a lot of labor. It's not profit, it's waste. Same with the ever increasing amount of admin. Why is that admin increasing? I estimate insurance or requirements created by insurance is part of the cause.

There is also a lot of other smells of a lack of a competitive market. Very opaque pricing, limits to how many hospitals can be opened in a region, needing paperwork to push against that limit, limits in residency slots, the entire hazing ritual of residency in the first place, limits in opening medical schools, ever escalating requirements to become a doctor, restrictions against doctor owned hospitals or clinics, the fact something like an epipen is still not out of patent and not having many clones by now, large barriers to make medical devices and medications, while simultaneously having great issues with generic drug quality, a horrible food system compared to Europe, while simultaneously having a much harder regulatory state medically compared to europe, etc.
