I'm not bitching about chads at all and I know perfectly well the nice guy line is an excuse. I think you've interpreted my post the wrong way.
Women don't want nice guys, especially after they've had the tingles during their 20's riding the alpha **** carousel, a lot of them have to settle for Mr. Nice when they finally realise they can't lock down any alpha and they're post wall. These are the women who are in generally miserable marriages/relationships later in life with beta providers who do nothing but repel them no matter how much stuff they can buy, nothing will ever come close to the tingles she got from Chad when she was mid 20's ****ing guys in restaurant toilets, hotel rooms or anywhere for the matter.
I think some people here are totally misinterpreting what you are saying... which is understandable it's a nuanced point.
But if you look around you see a lot of these patterns. You also see for example how a male doctor will hapilly marry a female nurse, but hardly ever the other way around. Hypergamy in full swing boyz. I think the problem is a lot of men find these things uncomfortable to hear about. Doesn't make it any less true.
Me? I just don't care, it is what it is.
As far as using the words alpha/beta to me it's just a simplified way of putting it. I don't generally think alpha and beta strictly exist rather a mix. But calling men alpha or beta is an easy way to drive the point home when having these kinds of discussions. You could use any words really, the cool guy or the uncool guy.
Cool guy = guy who may be seeing couple girls, sets boundaries, knows what he wants, doesn't take crapp off woman, won't be disrespected in relationships etc.
Uncool guy = thirsty for any female attention, gets walked over like a doormat, has no boundaries, lets his wife/girlfriend control him etc
Broad strokes here... because of course those traits aren't all limited to one or the other, but you get the idea.
