Yes, I agree with you that love can be "for the sake of the other", without it being a sacrifice. In that sense I like to complement Ayn Rand's Aristotelian love of "enlightened self-interest" with Erich Fromm's "brotherly love" as described in his "Art of Loving".
That being said, my question in this thread was somewhat on the side of this issue. My question was about the transition from Protestant Christian Altruist self-sacrifical ethics and towards a healthy, life-affirmative type of living that yields proper self-esteem and love. A big problem with the Lutheran self-sacrifical ethics is that one is only valued for self-sacrifice. Which means that one doesn't get to experience that others can enjoy to be with oneself and find value in oneself for who one is - who one is without sacrificing oneself. Who one is when one acts in one's enlightened or rational self-interest.
This switch in morals from Lutheran to Aristotelian is a revolution for the neurotic, and my question is if Rand has described how healing this switch of ethics can be for one's self-esteem, with particular regards to being valued by other people for being who one is without sacrifice.
