Both systems utilize ethical pluralism to formulate their structures, synthesizing multiple moral theories, but differing in how heavily each theory is weighted in the mix. The U.S. system focuses on libertarianism and deontology, prioritizing individual choice, free, capitalist market, and provider autonomy, while still incorporating limited egalitarian and utilitarian elements through public programs. In contrast, the U.K. system emphasizes egalitarianism, Rawlsian liberalism, and utilitarianism, focusing on equal access, fairness to the least advantaged, and maximizing population health, while still allowing some room for autonomy and private choice. Both systems utilize care ethics in their concern for patients and metaethical assumptions about what health care fundamentally is. The key difference is the balance: how much each system draws from these theories directly shapes how care is delivered, who receives it, and under what conditions. This shows that ethical pluralism is not just theoretical—the weight we give to different moral frameworks actively determines real-world policies and outcomes.
