 Nationality is just one further deep contingency (like genetic endowment, race, gender, and social class), one more potential basis of institutional inequalities that are inescapable and present from birth. Within Rawls’s conception, there is no reason to treat this case differently from the others. And so it would seem that we can justify our global institutional order only if we can show that the institutional inequalities it produces tend to optimize (against the backdrop of feasible alternative global regimes) the worst social position.
