Medical students on average face debt ranging from $119,000 to over $350,000. http://www.amsa.org/AMSA/Homepage/About/Committees/StudentLife/StudentDe...
That debt is a crippling constraint on young physicians and physicians to be- restricting choices to more fiscally rewarding fields and preventing physicians from doing amazing yet low paying work. It also skews the demographics of people entering medicine to those from better off socio-economic backgrounds.
Some doctors do make a great amount of money, the average, for pediatricians, family doctors, emergency room doctors, general surgeons, etc. are still in the $200,000 range- meaning that over 15-25 years are routinely spent in debt repayment for a profession with unparalleled social service.
