This paper briefly reviews the theory of social, negative, and cheap social capital and then explains the popularity and the high cost of cheap social capital. Next, this paper points out that our voluntary exchanges (which are enabled by prospects of mutual gain) and the high cost of involuntary exchanges (which are entered into in response to threats and defensive and destructive acts) both reflect our responses to the same physical and socio-emotional needs. Therefore, what differentiates our responses to similar needs are the relationships we have with others—whether they are social, negative, or cheap. Finally, this paper offers some suggestions for avoiding the high cost of cheap social capital.
Earned, inherited, and covenant commonalities enable persons and groups of people to develop sympathy and empathy for each other. The sympathy and empathy that one person or group has for another person or group is defined here as social capital. The absence of commonalities often results in relationships of apathy and antipathy that one person or group has for another person or group, defined here as negative social capital. People and groups that share negative social capital for the same person or group can form cheap social capital relationships characterized by the couplet—the enemy of my enemy is my strange bedfellow.
