Despite the early appeal of the jerks, however, in the end the girls realised that they were better off marrying the nice guys.
I really hate this analogy: Once the girls have had their fun, and are old, they settle with those who can provide for them And, although it has no direct relation, it always reminds me of Buffet and "saving sex for old age"[1].
But even then, it's not even always true. I'd wager the majority of these women end up in a cycle of jerks. You just selectively hear about the ones who give up, and settle. This isn't a matter of fate - it's a matter of perception.
