Rawls's Difference Principle as Compensation for Social Immobility

Outside academia, John Rawls's theory of justice—justice as fairness—has had little impact. This article is part of a broader project to rectify this. I offer a distinctive, second‐best, argument for Rawls's difference principle. The difference principle requires that inequalities in income and wealth are justified only if they benefit society's least‐advantaged citizens. My paper argues that, slightly‐modified, the difference principle is an excellent principle of redress in light of the UK's continued failure to give all citizens fair career chances. I show how we might realize the difference principle at the level of policy through tax rate reductions or negative tax rates. I conclude that if you don't want to accept the second‐best argument for the difference principle you must get serious about giving all citizens fair career chances. As I suggest, this task is extremely difficult.
