I'd love a good riot against Physicians in 2021. 2 centuries of corruption has lined their pockets and caused the rest of us to avoid medical care. I say this as I'm married to a doctor taking home 200-250k/yr. I don't mind shooting myself in the foot to save life.
I would look up the ladder before blaming physicians. It's not the high salary of the doctor that's inflated the cost of medical care. It's insurance, middlemen, overpaid administrators, and the general move to for-profit medicine that's to blame in my experience. Doctors make good money, but they also go through 8 years of expensive schooling to get there and are often just making ends meet for years after school.
Not in the industry, and these are complex issues, but the AMA is made up of doctors and is also a huge part of how medical professionals are qualified and has heavy influence on how funding for training, etc. is allocated. So while an individual physician may not be 'the problem', blaming the AMA (and so 'physicians') shouldn't be dismissed outright in favor of the other groups you mention, which are also part of the problem
