You MGTOW have mentioned about how women have become so choosy that they only want the top 10% or even less of men. Would it be plausible that women would want to share such a man?It will make it less likely for a woman to "settle for less",and much more likely for them to get the "alpha male" The "Hypergamy" you've mentioned also suggests that Harems were a norm in the distant past.

Bs tin foil hat logic or Welcome to Real life Harem Anime?
