Contemporary egalitarian political philosophy has become increasingly interested in the ways the international order may protect or undermine states’ capacities to deliver domestic egalitarianism. This paper draws on Miriam Ronzoni’s helpful discussion of the various different ways in which both philosophical and practical commitments can move beyond a contrast between a world of closed societies and a cosmopolis to explore how successful the theorizing prompted by that interest has been. Problems scholars like Peter Mair and Wolfgang Streeck have suggested the EU faces also suggest that there are difficulties views like Ronzoni’s have to overcome to usefully orient us towards the threats posed by the interactions between domestic and international politics. These problems can be usefully framed by what the intellectual historian István Hont called jealousy of trade and used to understand debates between members of what is commonly understood as the republican tradition, especially in the eighteenth century. Jealousy of trade revolves around the way that international economic competition intensifies international political competition, requiring the restructuring of domestic politics to ensure the survival of the state, which then further intensifies international economic competition. The ways of navigating and controlling the increasing costs of an increasingly belligerent international order eighteenth century political theorists found help illustrate the challenges contemporary internationalising egalitarians face. Isaac Nakhimovsky’s work on Johann Gottlieb Fichte’s closed commercial state is, I argue, specially useful given the similarity of some of Fichte’s commitments to those of contemporary internationalising egalitarians.
