Social control mechanisms, like forms of media, are never usurped they are simply absorbed in to the ever widening web of hierarchical dominion.

Economic theory is nearly as diverse as religion. As with the plethora of religions, there are nearly as many economic theories as there are economists, and I see no evidence of these theories usurping anything.

These are the social control mechanisms that exist in the phase of social integration. Their importance revolves around the control of the majority by the minority.

thats pretty myopic. you might try reading yuval harari's "Sapiens".
