> Doctors don't use unions. They instead artificially limit supply by erecting massive barriers to enter their workforce.

That's not true. Not sure about US but in many european countries doctors are organised in strong unions. There is otherwise no artificial supply limit initiated by doctors or hospitals.

In the US, while the AMA is technically a trade group and lobbying organization, it's goals/methods are similar to those of a union. It's often referred to as the Doctor's Union.
