 It is tempting to think that we can give a completely non-controversial definition of equal access to health care—much as we can do for equality of income—and reserve all controversy for debates about which departures from equality conform to acceptable principles of justice. If A earns $10,000 less than B, the inequality might be thought equitable by some if B works longer or harder than A, by others if B’s skills have a higher market value than A’s, and by others if B needs more than A does. Here our moral disagreements about appropriate distributive principles show up as disagreements about just or equitable income distribution, though there is no controversy about whether incomes are equal.
