Life (the Universe or the World) does not owe us a damn thing. We need to get over ourselves in thinking we "deserve" life to be "fair." "Fair" is arbitrary, a social construct imposed on us over feeling slighted, victimized, or other. But Life (the Universe or the World) does not care about our feelings.
The only social recourse is for us to treat people as we want to be treated and hope kindness can permeate our natural inclination to be combative a-holes.
Champion for the positive because life is forged by our choices, what we say, and what we believe. In other words, we get more of what we give out.
