> The debt isn't really that much. Probably the average is 200k. You can pay that off within about 1-2 years of residency, and interest rates tend to be low since they're low risk loans for banks to give out.

Please try looking at the numbers again. Assuming you pay off undergraduate loans, a private medical school will cost $30-45k a year (not including living costs, so tack on another $30k a year), so assuming ($150-$300,000) will be total assumed debt (not including books, unexpected expenses, etc) during those 4 years. Residency salary is basically stuck at around $50k/yearly for 3-5 years (based on residency type), you can contribute back to loans but there's not a chance you're paying that off in residency.
