The cosmopolitan strikes back: a critical discussion of Miller on nationality and global equality

According to David Miller, we have stronger obligations towards our co-nationals than we have towards non-nationals. While a principle of equality governs our obligations of justice within the nation-state, our obligations towards non-nationals are governed by a weaker principle of sufficiency. In this paper, I critically assess Miller's objection to a traditional argument for global egalitarianism, according to which nationalist and other deviations from equality rely on factors that are arbitrary from a moral point of view. Then I critically discuss Miller's claim that there is no culturally neutral currency with respect to which we may reasonably claim that people should be equally well off on a global scale. Furthermore, I critically discuss Miller's claim that cosmopolitanism undermines national responsibility. And finally, I turn to Miller's own sufficientarian account of global justice and argue that it exhibits too little concern for the plight of the globally worse off.
