How Egalitarian is Rawls's Theory of Justice?

Gerald Cohen's critique of John Rawls's theory of justice is that it is concerned only with the justice of social institutions, and must thus arbitrarily draw a line between those inequalities excluded and those allowed by the basic structure. Cohen claims that a proper concern with the interests of the least advantaged would rule out 'incentives' for 'talented' individuals. I argue that Rawls's assumption that the subject of justice is the basic structure of society does not arbitrarily restrict the concerns of political justice, as Cohen claims. Further, I argue that it does not allow 'deep' inequalities within a just basic structure. When properly understood, Rawls's theory of justice is strongly egalitarian, taken as a theory of fairness in the way the burdens and benefits of social cooperation are distributed, even if it is not as egalitarian as Cohen wishes.
