If morally arbitrary features (that is, blind brute luck) should have no impact on the distribution of wealth, then the vast inequality and the disparity in life prospects between countries is a moral catastrophe; birthplace is completely based on luck, and yet has an enormous impact on life prospects. I contend that those in affluent countries, who have benefited from the luck of birthplace, ought to work towards a more egalitarian world, in which luck plays as little a role in life prospects as possible.
