The market for doctors is fairly constant, it's very difficult to mint new doctors. Even if a state or university went through the enormous undertaking to create a new med-school, they would, at best, create 200-300 new doctors a year, a drop in the bucket.

The real solution is in alternative degrees like Physician Assistants or Nurse Practitioners. They can get degrees at half the cost of doctors and yet do 80% of a doctor's work.

Any real cost reductions in U.S. healthcare will have to include these alternative healthcare providers.
