 Radical political economists reject this reasoning. They carry the logic of the argument about the incoherence of legislative behavior through to the level of institutional and constitutional design. Constitutions are drafted by agents with political and economic interests that they seek to forward when they create the basic social, economic, and political institutions of the society. Incoherence may thus infect these institutions as well. The compromises over slavery in the US Constitution, for example, illustrate, when viewed against the democratic and equality elements of the document, such incoherence. Radical political economists thus reject the claim that the law is designed and hence reject instrumentalism altogether.
