Perhaps because we shouldn't be indoctrinating girls into thinking that their life is less meaningful if they don't find that perfect guy that is going to someday enter their life and make all their problems go away? You don't think that girls have anxiety spending significant amounts of time trying to look thinner, apply make-up, put every hair in its proper place, trying to make the impossible attempt to mimic a genetically fortunate super-model currently plastered across a magazine cover dictating what society finds appealing, all of which for the sole purpose of making sure that, one day, when that Prince Charming finally walks into her life, she can make sure that he will notice her and not blech in reaction.
