When did we begin to see an opening up of non-monogamy in marriage?
My argument is that in the 1970s free love and non-monogamy had a certain chic to them, but they didn’t have solid foundations in demography, economy, or technology.
Today, the idea of openly non-monogamous marriages has no political chic to it, but it does have a more solid foundation in demography (we live longer and are healthier than ever), economy (women earn their own paycheck, and don’t rely on the sexual contract in marriage for their meal ticket), and technology (we’re connected to people more than ever).
So marital monogamy is under greater stress today. And I think it’s being deliberately rethought and re-evaluated by a post-romantic generation that sees the main function of marriage as friendship, an establishment of a home base — not sexual passion and fidelity, per se.
