Often writers state a presumption in favor of equality in a form such as the following: “Differences in treatment of persons need to be justified.” . . . But if I go to one movie theater rather than to another adjacent to it, need I justify my different treatment of the two theater owners? Isn’t it enough that I felt like going to one of them? . . . It is not clear why the maxim that differences in treatment must be justified should be thought to have extensive application. Why must differences between persons be justified? Why think that we must change, or remedy, or compensate for any inequality which can be changed, remedied, or compensated for?
