A recent theorist, Jonathan Quong, proposed a new contribution to left-libertarian literature that is inspired by Rawls emphasis on social cooperation in his article Left- Libertarianism: Rawlsian not Luck Egalitarianism. This paper seeks to generate more detailed insights from Quongs proposal in the context of left-libertarianism and metrics of egalitarian justice and provide an analytical comparison. The surprise of Quongs project is that his metric is an intervention into distributive justice, instead of egalitarian justice, which is an intriguing step for left-libertarian theories.
