Contemporary Western societies are often criticized for being excessively individualistic. One interpretation of this claim is that their citizens mainly care about their own well-being and not so much about that of others or about communal bonds. Another, complementary interpretation that I develop here argues that our ideas in economics and about justice overestimate the contributions individuals make to economic production. Recognising the extent to which our productivity and thus our standard of living depends on the cooperation of others has a humbling effect on what income we can legitimately think we are entitled to.
