Very true!
As for your claim about the "popular guys being a success", I would say that is true at the private, selective school I went to, but when you get to your Joe Schmoe average public high school, the bully/jock types usually wind up sitting on their a-s at the tavern, talking about the good old days, while the geeks they teased were smart enough the get out of that hole.
Its all very complex. Charm without brains can only get you so far, and vice versa.
