I think if more primary care physicians can go back to a no insurance, flat-fee model and insurance is saved for urgent, emergency, specialized and long term care then Americans can live healthier and save money (neither of which is good in the eyes of for-profit healthcare and insurance), doctors and general practitioners will actually do what they enjoy and all around increase the efficiency of healthcare in the US.
