>This 'contract' between the sexes was advantageous to beta men, women over the age of 35, and children, but greatly curbed the activities of alpha men and women under 35 (together, a much smaller group than the former one). Conversely, the pre-civilized norm of alpha men monopolizing 3 or more young women each, replacing aging ones with new ones, while the masses of beta men fight over a tiny supply of surplus/aging women, was chaotic and unstable, leaving beta men violent and unproductive, and aging mothers discarded by their alpha mates now vulnerable to poverty.
