This paper defends a global principle of equality of opportunity, which states that it is unfair if some have worse opportunities because of their national or civic identity. It begins by outlining the reasoning underpinning this principle. It then considers three objections to global equality of opportunity. The first argues that global equality of opportunity is an inappropriate ideal given the great cultural diversity that exists in the world. The second maintains that equality of opportunity applies only to people who (...) are interconnected in some way and infers from this that it should not be implemented at the global level. The third, inspired by Rawls's The Law of Peoples, maintains that it is inappropriate to thrust liberal ideals (like global equality of opportunity) on nonliberal peoples. Each of these challenges, I argue, is unpersuasive. (shrink)
