Women perceives things like that. All women wants an alpha male, alpha sons and stuff. All mothers are disappointed if they have a betamale, as a husband or as a son. Motherly love, however, usually compensates and beta boys can grow up without that much traumas.
Now, what women doesn' understand is that there can be only that much alpha males. Women by large don't even understand what alpha male is. Alpha male is a man, who spend 95% of his awake time outside of his home. He is absent to his wife. He expects his wife to do as told. Otherwise he is not an alpha, but some half.
Beta males have the life come easy. They blend in with others, with no effort. Nobody thinks they are a threat. Beta males are the least stressed people in the world.
Oh well. I am my self a sigma male. I recommend to your next incarnation to try this formula out. All the benefits and good parts of an alpha and beta. You really don't give a shit about social games and hiararchies, you get what you want, you are not a socio- or psychopath but instead very emphatic, almost to the point of a clairvoyant. You just know instantly who are the good guys, who are the bad guys. You can focus, almost on autistical level on some task you have set for your self. You work for your self. You are your own boss. You hate the idea, that you would have people under your command..
Sigmas are the wet dream of every women. Han Solo, Indiana Jones.. Lestat the vampire (when those were still cool), these are the archetypes of a sigma male. People thinks they are alphas, but they never command anyone, they don't have their own wolf pack.
