There is an older argument about motivation and different tiers of need, a not insignificant part of which is self awareness, self-esteem, social recognition and accomplishment. I do not recall a need for societal superiority being defined as a positive motivator.
Is that Maslow's hierarchy of needs and all that? I don't think the monarchy should be defended on the basis that it's good for HM's self-esteem! On the other hand some antediluvians might argue that her 'societal (how about 'social'?) superiority' was good for us, that 'knowing your place' can sometimes make you feel better about yourself.
