Women who don’t settle may be delusional about the caliber of man they think they deserve given their current age/fertility, beauty, and lack of purity both sexual and psychological - but unlike the more pragmatic women who do settle, their delusionally high expectations egotistically prevent them from using the average man for her self-betterment.
So in a perverse and wholly unintended sense, her entitlement actually renders her less selfish than more modest and more practical women who do settle, because in being true to (but wrong about) what she thinks she deserves, she is alone rather than using a man she feels is beneath her. Not because she is more inherently virtuous and expressly desires not to burden, but because she is more egotistical. And so although that ego is keeping her single and childless, it is also stopping her from parasitically using a man she does not respect or desire and views as lesser for convenience and material gain, and so poetically for all her vain and self important entitlement, she actually does the average man a kindness in not burdening him with her.
A fool she may be, but for all her delusions and flaws, an unappreciative parasite she is not.
