Practicing medicine
must be lucrative because it costs an individual student around $240,000 in tuition for the M.D. itself, excluding cost of living.
Doctors are made out to be predatory vultures, but unless they come from money they must undergo massive debt burdens that they are not able to even begin paying down the principal on until they're well-into their thirties. Imagine the feeling of taking out half-a-million dollars in student loans to cover both undergrad, and graduate-level training. After that look forward to your 80-hours a week of residency making below hourly minimum wage. [1]
Make medical school free, and you'll have people lining up the door to practice for low-cost. Make it half-a-million pay-to-play, and you'll have people desperately clawing their way out of debt so that some day they can have a family and own a home after a decade of hellish training.
Cut the docs some slack. They're taking on unimaginable debt burdens for a job that often isn't in the same universe of cushiness as something at FAANG (inspecting that anal fissure in the ED at 3am with perks including, well, hospital food), but involves an tremendous service to society.
