"In subsistence economies with general convex technology and rational optimising agents, a new, axiomatic approach is developed, which allows an explicit analysis of the core positive and normative intuitions behind the concept of exploitation ... the crucial insights of exploitation theory are generalised, proving that every agent's class and exploitation status emerges in the competitive equilibrium, that there is a correspondence between an agent's class and exploitation status, and that the existence of exploitation is inherently linked to the existence of positive profits."
