Unlike the rest of the world, the entire medical and healthcare system in the United States is for profit. And when there’s money to be made, you can almost be sure that someone will abuse the system.
Health insurers implement secretive practices that stop people from accurately knowing what they’re being charged. Companies like TeamHealth (owned by Blackstone) have such an influence over the business of the medical industry, that chances are your doctor or nurse is employed by them.
And investment firms like Vanguard and Blackrock own at least a part in almost every single major publicly-traded hospital or healthcare system in the entire nation.
And of course, as you might expect, it’s the poorest people in the nation who always suffer as a result of this. People who can’t afford insurance, and even beg people not to take them to hospital when injured, because they likely won’t be able to afford treatment.
