ABSTRACT
This chapter explores why doing or receiving one's share sometimes invokes fairness concerns as well as when, or under what circumstances, it does so. One way to understand a fair share of the cost of a given scheme is to divide the total cost by the number of beneficiaries and assign all beneficiaries an equal share. To benefit from the efforts of others without contributing one's fair share is a form of expropriation. When the labor and efforts of others enrich one's own life without proper compensation, the other is treated as a mere instrument for the development and promotion of one's own wellbeing. For the nature of one's share of the burden, along with the amount of benefit to be enjoyed, is most likely a consequence of the nature of the associative relationships constitutive of the cooperative activity in question.
