 So we need to ask about the circumstances in which justice requires a substantively equal distribution of advantages. One rather obvious case occurs when the members of the group within which the distribution is going to occur have no relevant distinguishing features, so there are no grounds on which some can claim greater shares of benefit than others. Suppose a group experiences a windfall gain for which no-one can claim any credit: a pot of gold somehow appears in their midst. Then unless any member can make a justice-related claim for a larger-than-equal share – say that she has special needs that she lacks sufficient resources to meet – an equal distribution of the gold is what justice demands, since any other distribution would be arbitrary. Equality here is the default principle that applies in the absence of any special claims that can be presented as reasons of justice.
