Thanks to the Affordable Care Act, 31 million previously uninsured Americans are about to gain access to health coverage. But who's going to treat them? The Association of American Medical Colleges estimates a shortfall of 63,000 doctors by 2015—and one of 130,000 doctors by 2025. U.S. medical schools would have to graduate seven times more doctors that year alone just to keep pace. We need more doctors in America, and we especially need more of the small, primary care practices that often represent the only health care available in underserved areas. Unfortunately, market dynamics and policy changes are turning the independent family doctor into an endangered species.
