That’s what I mean when I refer to facile ideological reactions. For many people, “profits” are the problem, and they don’t care that health insurers on average are less profitable than Subway franchises. It’s just the mirror image of people who say the New York MTA is a disaster because the government is running it, and don’t care that governments in other countries manage to run cost-efficient train systems.
Big players like United just shuffle money around because they own the entire vertical market. Their insurance arm is regulated so they just move the money to to their service provider arms like Optum which are unregulated with uncapped profits.
The real players are big corps like United and CVS, who control the whole vertical of provider and payer. They own the doctors, the pharmacies, and the insurance.
