In this article we argue for a world in which open borders are the rule and not the exception. This argument is based on the general recognition of ius migrandi as a basic right of persons. An open-border immigration policy is preferableat least from a normative standpointto the typical policies designed to control or block borders through the simplistic mode of constructing walls. On the basis of a global conception of distributive justice as suggested by cosmopolitan egalitarians, we claim that open-door policiesor, failing in that, the implementation of a system of economic compensation for poor countriesprovide powerful means to respond to the enormous inequalities that exist between countries and represent an appropriate way to order current migratory flows.
