 Now consider the following possibility. Imagine that we are living in a liberal democracy with a full array of social roles in which people act in a public capacity. But imagine that our society is a private society: citizens care only about their own private affairs. In order to ensure that various public roles are filled, our institutions create private incentives for people to take on these responsibilities. High salaries draw people into positions as judges and legislators, and mutual surveillance gives these people private incentives to carry out their duties. Suppose that our institutions are well structured and private incentives are adequate to fill all of the important public positions. Is there anything missing in our society? Does our society suffer from a moral defect of some kind?
