According to the incentives argument, inequalities in material goods are justifiable if they are to the benefit of the worst off members of society. In this paper, I point out what is easily overlooked, namely that inequalities are justifiable only if they are to the overall benefit of the worst off, that is, in terms of both material and social goods. I then address the question how gains in material goods can be weighed against probable losses in social goods. The (...) ultimate criterion, so my idea, is how these gains and losses affect a person’s ability to reach her goals in life. Based on the idea that goals in life cannot be taken as given, I conclude that the absolute material gains are negligible compared to the losses of social goods and the disadvantage in the relative position caused by material inequalities.

In his book, A Theory of Justice, John Rawls suggests that a theory of social justice is satisfactory only if it has both of two characteristics. First, it must be capable of serving as the “public moral basis of society”. That is, it must be reasonable to suppose that it would be strictly complied with while serving as the public conception of justice in a society which is in favourable circumstances—a society in which the people would strictly comply with any (...) public conception of justice if the strains of commitment to it were not too great, given the general facts of psychology and moral learning. Second, a theory of justice must characterize “ … our considered judgements in reflective equilibrium”. (shrink)
