Pffft! First of all, there’s no such thing as alphas. That’s a concept invented by guys who are obsessed with the dominance hierarchy. In the wolf world, the alpha male is simply the daddy of the pack and the alpha female may actually be the ultimate leader.
And secondly, if you look out the window you will see all kinds of people paired up. Women go for all kinds of traits, and although confidence is very attractive, as previously stipulated, men think it’s more important for men to be “a good provider” than women do.
And there are many reasons why men make up most of the homeless (including but no limited to the high proportion of homeless veterans), but most of the world’s poor are female, including in this country.
