Political Equality and Political Sufficiency

Abstract

AbstractThe distinction between equality and sufficiency, much discussed in the distributive justice literature, is here applied to democratic theory. Overlooking this distinction can have significant normative implications, undermining some defences and criticisms of political equality, as I show by discussing the work of three prominent democratic theorists: Thomas Christiano, David Estlund, and Mark Warren. Most importantly, Christiano sometimes defends egalitarian conclusions using sufficientarian premises, or worries about inequality in situations where insufficiency is also part of the problem; inequality above the level of sufficiency is not always as troubling. Estlund makes the reverse error. He attacks rather than defends political egalitarianism, but insufficiency seems to explain some of his concerns. Nonetheless, I show that political egalitarians may need to specify a sufficientarian threshold, to avoid levelling-down objections. Democratic theorists should thus take seriously the distinction between political equality and political sufficiency. More generally, political theorists and philosophers should be aware of omitted variable bias and interaction effects due to conceptual stretching arising from under-theorised distinctions in their thought experiments.
