I'm all for free healthcare, but this is a legitimate concern due to exorbitant education costs. Doctors often enter the field with high 6 figure or low 7 figure debts, with the expectation they'll make enough to pay it off quickly. I can't see a fair path to lower salaries without subsidizing outstanding debts.
First, let's not use the phrase "free healthcare" because it's never going to be free. It's more about how we as a society choose to pay the cost. Secondly, reducing the barriers to getting a good medical education could easily be part of the solution. I also think there is a clear downward spiral that occurs when doctors earn exorbitant income, then medical school becomes more in demand, then prices increase, then salaries have to compensate and so on.
Do any of these bills attempt to dig us out of that doctor debt / high salary hole?
How much should they be allowed to earn?
However much they can get someone to pay them! So long as they're aren't also using their cartel power to reduce the availability of medical care. Which they are.
How would they get anyone to pay anything if their services are being offered by the government as a basic human right? They lose all bargaining power if they can't refuse their services.
If the government offers too little money, the supply drops and you get quotas, waiting lists, and denied treatments.
