Restrictive medical school admissions aren't the problem. The real bottleneck is in the number of residency slots available for medical school graduates. Every year people graduate with an MD degree but are unable to actually practice medicine because they can't get matched to a residency slot.

Most residency programs are federally funded, although some are also funded directly by teaching hospitals. If you want a larger supply of doctors then lobby the federal government for more residency program funding. And knock off the uniformed conspiracy theories.
