At the heart of finding a way to manifest social property is the tension between planning and markets. In this section we insist that that this is not a matter of planning versus markets but of discovering creative institutional mechanisms that structure the proper place of planning and markets. Marx rightly argued that praising the voluntary and efficient nature of markets apart from the underlying social relations in which they’re embedded fetishizes markets. But markets are also fetishized when they are rejected as an absolute and treated as having a life of their own independent of those underlying relations. The place of markets under socialism is a matter of both principle and practicality — and dealing creatively with the contradictions between the two. Some markets will be banished under socialism, some welcomed, and some reluctantly accepted but with constraints on their centrifugal antisocial tendencies.
