Look, it's simple really. We've got this planet with a few billion people and assorted plants and animals living on it. So the most obvious rules are:
- Don't screw up the planet, because that's where everything comes from. Got that? EVERYTHING!
- Every human being, every single one including the ones born just now .... and now ... and now ... deserves a share of what that planet has to offer.
Sure some people are smarter, or more adventurous, or sexier or better at hitting a ball with a stick, but we're all human and we all deserve to live comfortably. Maybe some people deserve to be wealthier because of their talents and abilities, or even because they had the good sense to be born to families that were wealthier, but that should be the icing on the cake.
The basics for survival and comfortable living should be for all.
It's just that simple.
