Sheleff states that contemporary liberalism, particularly as practiced by philosophers of law, answers the question to what extent coercion may be used to oblige people to live certain forms of life and abandon others. Raz, however, advances in the direction of applying liberalism to questions relative to the economy. Sheleff believes that Raz, although heading for the right direction, still does not push far enough. For Sheleff, liberalism cannot stand satisfied unless it answers the question to what extent coercion may be used for the sake of economic justice.
