No no don't let the Physician cartel get out of this. Year over year they get at least 5% pay increases with US tax dollars. Not to mention, they get private pay increases by weaponizing the ACGME to keep residency slots low. Residency does not need to be paid. Outside of the Medical industry, people pay for their college. For some reason Physicians make tax payers pay for their education and a decent salary.
Residency is not college, residents are practicing physicians that are providing considerable value to society and in many cases they are paid appallingly little for the amount that they work.
