Your same arguments apply in the other direction, you know. It's not just women interested in the most desireable men, it's also that men are interested in the most desirable women.
I'd say that is quite the oversimplification you have there. You might want to check some of your base assumptions like how women only desire wealth and looks as well as men only desiring youth and looks. Generalizations tend to be wrong more often than they are right in my experience, and this seems no exception.
