Money don't do sh*t for attracting girls.
Your argument is logical enough, but simply proven false through experience. Same with physical strength, and looks, and all that other social stuff.
If you want a biological reason why I make friends with "cool" guys (and I have other "non-cool" friends, too) is because they are fun, and when we are fun together we build endorphins due to laughing and enjoying ourselves, and since it creates good feelings in the body, there is a mutual desire to spend time together. Hence friends. It's little to do with the logical motive of having sex with their girl friends (not girlfriends), and definitely not a core motivation.
What lead you to conclusions like these? Just curious. I would take a long hard look at yourself to fine out how you reached these thoughts.
Oh wait, taking a long hard look at yourself is evolutionarily selected against, as it just wastes mental energy when you could be hunting for food or having sex. My bad.
