 In contrast to free-standing approaches to the justice of health inequalities, derivative approaches locate the injustice of unjust health inequalities with their unjust causes. Norman Daniels (2008) offers the most prominent example of this approach (see also Daniels, Kennedy, &amp; Kawachi 2000; and Peter 2004). His central claim is that, by a happy coincidence, John Rawls’ principles of justice regulate all of the principal social determinants of health (Daniels 2008: 82 and 97). Compliance with these principles, Daniels (2008: 82) claims, “will consequently flatten the socioeconomic gradient of health as much as we can reasonably demand” with the result that “social justice in general is good for population health and its fair distribution”.
