After recalling that Calhoun study, I feel even stronger in my convictions that sex must be freed and the "nuclear family" must be nuked for people to be happier with these social arrangements in our huge modern society. Of course, the only logical way for this to happen is to create even denser networks, ala the tribes that we were once a part of. Will this necessitate a move away from dense populations? Or can a polyamorous society succeed with the current infastructure?
THAT is one hell of a question that I have yet to answer.
