As a layperson, it seems like we (patients / society) would benefit from having more doctors, i.e. opening up more residency slots and admitting more people to med school, but there's probably a lot I don't understand about the issue. Not sure if it's a lack of political willpower to do this, or if there are other reasons why the number of doctors we train is so restricted.
