Do the demands of egalitarian justice extend to the international realm? Some believe that a positive answer follows from a simple line of reasoning: where a child happens to be born is a morally arbitrary fact; accordingly, it shouldn’t unduly influence her life prospects, as will inevitably be the case unless economic inequalities between countries are ironed out. I argue that this style of argument overlooks an important problem concerning the extent to which a person can unilaterally impose enforceable obligations on others by choosing to have a child. I maintain that properly egalitarian duties of distributive justice only arise when this problem of unilateral imposition has been solved. I further argue that solving the problem requires robust political institutions that do not exist in the international context—institutions instantiating a version of what John Rawls calls pure procedural justice, to ensure that the aggregate result of individual reproductive choices is acceptable to all.
