 An equally serious objection arises from the fact that some of the institutions that actually exist are morally indefensible. Let us imagine a thoroughly horrible social institution – slavery. Suppose some unfortunate individual is governed by that institution. Suppose the institution contains rules that say that slaves who are strong and healthy shall be required to work without pay in the cotton fields. Suppose this individual is strong and healthy. Consider the claim that he deserves to be required to work in the fields without pay in virtue of the fact that he is strong and healthy. AID implies that this desert claim is justified. That is as preposterous as it is offensive.
