Justice in Social Exchange.

"Justice is the good of others," reiterated Aristotle. George C. Homans conceptualizes "social behavior as an exchange of activity, tangible or intangible, and more or less rewarding or costly, between at least two persons." Homans defines the rule of distributive justice in the following words: "A man in art exchange relation with another will expect that the rewards act each man be proportional to his costs, the greater the rewards, the greater the costs-and that the net rewards or profits, of each man be proportional to his investments, the greater the investments the greater the profit. If the statement that rewards are expected to be proportional to cost is meant to imply that the proportion is constant, it is clearly not correct, since people realize that the costs they must incur to obtain certain benefits depend on their scarcity. if this statement, on the other hand is merely meant to imply that people supply increasing rewards to others at increasing costs to themselves in the anticipation of receiving increasing rewards in return, it merely repeats the basic principle of social exchange without adding anything new.
