The oldest problem of humanity Ever since humans have lived in groups, they have collaborated and shared responsibilities. But how can everyone be fairly paid for their work? In the family, everyone usually contributes without compensation, expecting the family to help them. This already causes a lot of conflict among kin, so how could stranger collaborate in that way?
