Harry Brighouse and Adam Swift propose that it would be morally wrong to insist on complete fulfillment of FEO, because parents have legitimate interests in helping their children to have good life prospects. There is a legitimate interest in acting for their children's sake, and also a legitimate interest, an important constituent of the parent's good, in creatively expressing themselves in how they fulfill the parent role and in developing and sustaining special asymmetrical friendship bonds with their children that are unique to parent-child relations. As they put it, parents have a “nonfiduciary interest in being able to play a fiduciary role” with respect to their children” (Brighouse and Swift 2009: 54.). They work to distinguish inequality-promoting parental behaviors such as reading bedtime stories to children that are essential to achieving the special values of parent-child relations and other inequality-promoting behaviors such as sending children to expensive private schools that do not make essential contributions to parental relations and that might be discouraged or taxed or even prohibited without inflicting damage on parent-child relations.
