John Rawls construed the Theory of Justice as central to political philosophy, and defended a series of purportedly egalitarian versions of such a theory. This essay points out that Rawls' philosophy became increasingly influential during precisely that period in recent history – the last quarter of the 20th century – in which global inequality increased most dramatically, and explores some possible explanations of this peculiar fact. It concludes by arguing that methodological defects make his approach fundamentally misguided: early versions of his theory are too abstract to be of relevance to understanding politics or as guides to action, and later ones too parochial.
