The granddaddy of all the "social" scams, however, is the "social contract." That's what replaced the "divine right of kings" in the 17th and 18th centuries, when it was falling apart. This is, in Wikipedia's (slightly edited) words,
a theory or model that addresses the questions of the origin of society and the legitimacy of the authority of the state over the individual.
In other words, this was the new explanation of why it's right for one group of men to rule over other men. Wikipedia continues:
Arguments typically posit that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority of the ruler in exchange for protection of their remaining rights.
