@JLNobody,
I believe that's just a convenient illusion...on a strict self inquisitive closer look, in the very least the first reward you have is a sense of usefulness that immediately alleviates your anxiety's or compensates lesser moral moments in your life, and that's precisely why I feel ashamed of ever announce whatever altruistic actions I take...I equate the problem with physics and its processes,
energy is always traded and never lost...so if people can act altruistically some gain must exist, you can't be just dissipating effort and energy...most people are buying moral superiority over those who don't act altruistically and make it quite loud so that everybody know how good and wonderful they are, that isn't just kitsch and self indulging but essentially it is provincial and stupid...
