Does The Spirit Level refute Rawls?
For me as a philosopher, the thing about The Spirit Level that is most exciting is that as a study of the pervasive harms of inequality it strongly suggests that John Rawls’s ‘difference principle‘, which says that inequalities are OK provided that they materially benefit the worst off, a principle that has dominated political philosophy for 40 years, is simply wrong. Empirically wrong. Which means that put into action ‘the difference principle’ will create a worse society, across a whole index of measures. Perhaps surprisingly, it will make virtually everybody, and certainly the worst off, worse off. (Or at least: worse off than they could be if an alternative way of ‘organising inequalities’ – a more egalitarian way – were settled upon.) Even if they have more money or more things (are ‘materially better-off’), this will not translate into an improved quality of life: on the contrary.
