Rawls defends an egalitarian conception of justice without invoking a desire for equality, as he believes it is unlikely that such a desire could be widely shared within a society. Furthermore, he believes that this aspiration, particularly among the poorest, may be unrealistic. This position is not inconsistent; egalitarian results can undoubtedly be achieved based on selfish motivations. However, this approach lacks a fundamental emotional driving force. This is probably because, although Rawls believes that fair institutions will ultimately develop a sense of justice, he does not envisage the formation of a public education system based on equality that would support the adoption of the difference principle.
