The state of family medicine and primary care in the United States is precarious, afflicted by chronic underinvestment. Family physicians and their allies should not expect different policy outcomes without adopting a different theory of change and tactical approach to reform. I argue: (1) high-quality primary care is a common good, as asserted by the National Academies of Sciences, Engineering, and Medicine; (2) a market-based health system captured by extractive capitalism is inimical to primary care as a common good;(3) professionalism has both aided and constrained family physicians as agents of change for primary care as a common good; and, (4) to actualize primary care as a common good, family physicians must embrace "counterculture professionalism" to join with patients, primary care workers, and other allies in a social movement demanding fundamental restructuring of the health system and democratization of health that takes power back from interests profiting from the status quo and reorients the system to one grounded in healing relationships in primary care. This restructuring should take the form of a publicly financed system of universal coverage for direct primary care, with a minimum of 10% of total US health spending allocated to Primary Care for All.
