 The second obstacle is that utilitarianism judges outcomes by totalling up utility levels, and has no independent concern for how that utility is distributed between persons. So even if we set aside the currency issue, utilitarian theory seems unable to capture justice’s demand that each should receive what is due to her regardless of the total amount of benefit this generates. Defenders of utilitarianism will argue that when the conduct-guiding rules are being formulated, attention will be paid to distributive questions. In particular, when resources are being distributed among people we know little about individually, there are good reasons to favour equality, since in most cases resources have diminishing marginal utility – the more of them you have, the less satisfaction you derive from additional instalments. Yet this is only a contingent matter. If some people are very adept at turning resources into well-being – they are so-called ‘utility monsters’ – then a utilitarian should support a rule that privileges them. This seems repugnant to justice. As Rawls famously put the general point, ‘each member of society is thought to have an inviolability founded on justice which….even the welfare of every one else cannot override’ (Rawls 1971, p. 28; Rawls 1999, pp. 24–25).
