What came first: the chicken or the egg? It's a cycle and each one is causing the other.
Women are hardwired to be the biologically more selective sex. Intercourse for a women means potentially 9 months of pregnancy and 18 years of raising a child. Intercourse for men means they get a nut and can dip out if they want to get another nut with potentially multiple women in those same 19 years.
So women want men who have money, ambition, and are at least decently attractive. Beta males retreat to video games and throwing money at e-thots, thus making themselves physically and financially unattractive to women, thereby taking themselves out of the dating pool. Women in response have fewer men to choose from and therefore chase the same group of men.
Beta males can choose to break the cycle by getting an education, going to the gym, and joining social activities. I have no pity for men who whine about "Chads taking all the women."
