Can Free Med. Schools save Primary Care?

My brother showed me this interesting op-ed in the New York Times today arguing that the primary care dilemma in America can be saved by a simple solution: subsidize medical school for doctors!

Okay, okay - so it's more complicated than simply letting future rich doctors go to school for free.  The reality is clear: there's a severe shortage of primary care docs in America because there's no $$.  If you're a physician in training, why settle for only giving patients physical exams (open your mouth, say ahhh!, etc.) and referring the sick ones to other docs when you could be a specialist?  There's a financial incentive for every prospective doctors to be a surgeon, cardiologist, or some other kind of specialist because - ka-ching! - that's where the money lies.  

So, what do the columnisst propose?  Let everyone go to med. school for free.  Now, if after you finish med. school you decide to continue your primary care training - that's also free.  But, if you want to become a specialist, you pay (instead of being paid, as the system currently is).  The best part?  The plan subsidizes itself - the money the specialists pay for further training covers the cost of medical school for all doctors.

With a simple switch, there's an incentive for all students to go into primary care.
