> The defenders of the system are entirely medical workers
No, that's not correct. Doctors and nurses largely despise the US system. They are incredibly overworked and streched too thin to provide great care (and most of them are in it at least partially because they enjoy caring for people).
The US system only benefits the middlemen who provide no healtcare value: insurance companies and hospita/clinic adminitrators.
The defenders of the system are entirely medical workers and owners.
The various medical lobbies/cartels are incredibly strong.
