The Trump Administration's recent attempts to repeal the Affordable Care Act have reignited long-running debates surrounding the nature of justice in health care provision, the extent of our obligations to others, and the most effective ways of funding and delivering quality health care. In this article, I respond to arguments that individualist systems of health care provision deliver higher-quality health care and promote liberty more effectively than the cooperative, solidaristic approaches that characterize health care provision in most wealthy countries apart from the United States. I argue that these claims are mistaken and suggest one way of rejecting the implied criticisms of solidaristic practices in health care provision they represent. This defence of solidarity is phrased in terms of the advantages solidaristic approaches to health care provision have over individualist alternatives in promoting certain important personal liberties, and delivering high-quality, affordable health care.
