John Rawls is arguably the most important political philosopher of the past century. His theory of justice has set the agenda for debate in mainstream political philosophy for the past forty years, and has had an important influence in economics, law, sociology, and other disciplines. However, despite the importance and popularity of Rawls's work, there is no clear picture of what a society that met Rawls's principles of justice would actually look like. This article sets out to explore that question.

This article seeks to defend prioritarianism against a pair of challenges from Michael Otsuka and Alex Voorhoeve. Otsuka and Voorhoeve first argue that prioritarianism makes implausible recommendations in one-person cases under conditions of risk, as it fails to allow that it is reasonable to act to maximize expected utility, rather than expected weighted benefits, in such cases. I show that, in response, prioritarians can either reject Otsuka and Voorhoeve's claim, by means of appealing to a distinction between personal and impersonal value, or alternatively they can harmlessly accommodate it, by means of appealing to the status of prioritarianism as a view about the moral value of outcomes, rather than as an account of all-things-considered reasonable action. Otsuka and Voorhoeve secondly claim that prioritarianism fails to explain a divergence in our considered moral judgement between one-person and many-person cases. I show that the prioritarian has two alternative, and independently plausible, lines of response to this charge, one more concessive and the other more unyielding. Hence, neither of Otsuka and Voorhoeve's challenges need seriously trouble the prioritarian

If solutions to the problem of inequality are to be as radical as reality now demands, what is instead required is a reimagining of what would be involved comprehensively to tame capitalism through democratic means. This will involve much further development of the kind of plurality of institutional and policy proposals sketched by Meade, and will involve both the private and public – individual and collective – forms of capital predistribution that Meade advocated. Piketty, like Meade, sees the need for both redistribution and predistribution, and both see that the institutional means necessary to create a more equal society will involve pursuing a plurality of parallel paths. It is closely in keeping with the spirit of Piketty’s Capital that the political and intellectual agenda ahead will be one that economics on its own cannot hope to encompass. It’s a vital agenda, with high stakes, and presents challenges to both academic researchers and political activists. On the success of this endeavour depends nothing less than the prospects for legitimate continuation of our economic system.
