If you don't do residency, you go work at Wendy's. I don't see any "shortage" of Wendy's cashiers. Interesting how that works. Why is it relatively simple to fulfill one need but not the other? Why can Wendy's hire affordable cashiers but no one except the wealthy can afford basic health care?
Don't give me the "but you gotta be smrat to do medicine" bullsh*t. Needing penicillin for strep throat is actually not much different from needing any other random ass thing, there's just a monopoly on providing it. Needing lovastatin for cholesterol is no different from any other random ass thing, except only one company is allowed to sell it. Restriction of supply to elevate prices, same goes with residency spots.
