And don't worry about NPs or other workers as they don't control whats keeping physicians down like corporate interests and lobbying.
The knowledge base,clinical productivity, and ability to grow with the science of medicine is clearly more evident if you see mid levels and doc after pgy1. Patients see it too, maintain integrity and patient care as a focus and the public is the one friend physicians don't want to lose.
Nurses are more middle management and have great labor conditions compared to docs. They farm out duties to techs and administer some meds, break on the reg, get OT and all the other stuff a person should be entitled to. Hospitals still pay it out cause there bottom line works and nurse unions lobby to keep themselves relevant
State hosptial licensure, medicare payments and facility eligibility has specific nurse staffing requirements per shift, floor, unit, patient.
You don't see that with docs, the existence of a medical director for some places is it. They do have requirements like a doc has to do an admission, orders, discharge summaries, certain procedures, etc. But that gives hospitals the ability to spread MD labor as thin as they want and payment is based on billing alone. An MD doesnt make money till the hospital does. The nurses don't allow their labor the opening to be abused because they are there on their shift and can move as slow as they want or do as little as they want and clock out.
There should be a line between encouraging productivity (if patient care is in mind) and giving a worker some security and stability. As well as being foundation of healthcare that cant be worked around like nurses have. Or else they will find cheaper labor to do as much of the MD work as they can get away with, bill the same, and pay the MD less
