Yes and no. Monogamy was an artificial social contract we built western civilization on.  Feminsts want it abolished and Chad's and hypergamy mammies always ignored its rules on the sly anyway.  Tinder killed it for normy females and mgtow are for the 80% of leftover men. Its gonna get messy but monogamy had to be strictly enforced at all levels to remain viable and im not sure people were all that happy under it especially with life spans into the 80-100 year ages.
