  Another issue emerges if one asks: why focus on individual persons rather than on groups? One might hold that it is not important that individual persons have equal life prospects, but it is morally valuable that men and women on the whole should have equal life prospects, that heterosexuals and non-heterosexuals should have the same life prospects, that people of different supposed races should have the same life prospects on the whole, and so on. To fill out this proposal one would need to develop a normative account that explains what sorts of group classifications matter for this purpose and on what grounds. Notice that one might be troubled, for example, if it is found that men have better life prospects on the average than women, because that would be an indicator that perhaps equality of opportunity and fair equality of opportunity are not satisfied. To be moved by this consideration is not to value equality of condition across groups per se.
