20/80 Theory

Anybody ever heard of this? 20% of men get 80% of the women, through their looks or money or power. Women are willing to share a "winner" rather than being with someone who isn't the creme de la creme (after all, we all deserve the best don't we?), leaving many men unable to find a partner. This may explain why you see girls trying to go after married guys. I don't particularly think it's true or false. I want to know what you think.
