Create government sponsored medical schools; lowering health care costs by adding more doctors into the system.

Create government funded medical schools to increase the number of medical doctors in the long run. More doctors would eventually lower healthcare costs by increasing competition among providers and giving patients more options.
The limited number of medical schools and high costs currently prevent many highly qualified people from becoming doctors.
Graduates could repay the government by serving in low income areas, the military, or veterans hospitals for an agreed amount of time.
