Every major work on material inequality in the 21st century owes a debt to Sen. But his own writings treat material inequality as though the moral frameworks and social relationships that mediate economic exchanges matter. Famine is the nadir of material deprivation. But it seldom occurs – Sen argues – for lack of food. To understand why a people goes hungry, look not for catastrophic crop failure; look rather for malfunctions of the moral economy that moderates competing demands upon a scarce commodity. Material inequality of the most egregious kind is the problem here. But piecemeal modifications to the machinery of production and distribution will not solve it. The relationships between different members of the economy must be put right. Only then will there be enough to go around.
In Sen’s work, the two critiques of capitalism cooperate. We move from moral concerns to material outcomes and back again with no sense of a threshold separating the two. Sen disentangles moral and material issues without favouring one or the other, keeping both in focus. The separation between the two critiques of capitalism is real, but transcending the divide is possible, and not only at some esoteric remove. Sen’s is a singular mind, but his work has a widespread following, not least in provinces of modern life where the predominance of utilitarian thinking is most pronounced. In economics curricula and in the schools of public policy, in internationalist secretariats and in humanitarian NGOs, there too Sen has created a niche for thinking that crosses boundaries otherwise rigidly observed.
