Makes a good story. The truth is that most women will 'target' a higher status man for his seed hoping that the man will commit, elevate her status, take care of her and the baby.
This is a very high risk strategy since the man will usually be married with one or several families but if it works the payoff is good.
If it doesn't work the woman will just lay low and wait for a man in her class to marry her.
If it is all about intelligence and looks, then these women would be camping at the medical, law and engineering schools harvesting the genes of goodlooking, intelligent virile students. I am sure they will have no qualms about donating their DNA.
Life is short. Live passionately.
