Justice, Luck, and Pairwise Comparisons

This chapter extends the anti-anti-luckist programme to political philosophy, and to the doctrine of luck egalitarianism in particular. Luck egalitarianism affirms that unchosen relative inequalities between agents are unjust. It condemns inequalities that are due to ‘brute luck’, and upholds inequalities that are due to ‘option luck’. Though it can be easily enough stated, luck egalitarianism is actually a complex theory with two separate components: egalitarianism and anti-luckism. Standard luck egalitarianism’s commitment to pairwise comparisons makes it vulnerable to what Susan Hurley calls the ‘Boring Problem’. The Boring Problem points out that any two agents in a pairwise comparison are bound to lack control over the relevant income gap between them, because each of them controls, at best, only one side of that comparison. Though Hurley herself is relatively dismissive of the Boring Problem, it is contended here that, when it is properly appreciated, it inflicts huge damage on luck egalitarianism, which needs in turn to be re-organized as a ‘baseline-sensitive’ theory that dispenses with pairwise comparisons. Baseline-sensitive luck egalitarianism makes decent progress on a number of critical fronts, particularly Saul Smilansky’s ‘Paradox of the Baseline’. But even this form of luck egalitarianism is still open to a worry about how it understands the relationship between its egalitarian default and its case for permissible inequalities, and it has less to say than it should about the structural aspects of a social system that generate inequalities.
