Abstract
This paper aims to show that fairness in trade calls for relaxing existing WTO rules to include a greater liberalisation of labour migration. After having addressed several objections to global egalitarianism, it will argue, first, that the world’s rich and the world’s poor participate in a same multilateral trading system whose point is primarily to reduce trade barriers, and hence to establish global economic competitions, in order to raise their standards of living; second, that these competitions are subject to requirements of formal and substantive fairness; and, third, that the substantive fairness of the competitions that are taking place in the field of trade in goods is likely to require a greater liberalisation of labour migration, especially low-skilled labour from developing countries.
