How would you even determine how much you need? You labor under the illusion that you're an intelligent being. Evolution does not care about "enough"... because there is no way to determine what "enough" is. What is enough today will not help you survive tomorrow's famine. Best stock up now. If you were so smart, you'd get that. What others call greed is subconscious anticipation of calamity.
> What is enough today will not help you survive tomorrow's famine.
Tomorrow's famine will be caused by you (read: those behaving as you describe) not knowing when enough is enough. Best preserve what we have, rather than waste it all in a frantic bid for number-goes-up.
Possibly. Or maybe it will happen anyway.

That's mostly leftist moralizing on your part.
• If you wish yourself maximal reproductive fitness, then all humanity will be your descendants, and the next few centuries of all human interest is your interest.
• The iterated prisoner's dilemma is a classic economic argument, by which Tragedy of the Commons-type behaviours can be averted. (Garrett Hardin's 1968 paper is a load of nonsense.)
I'm not sure what would contrast my earlier "leftist moralizing", because I have absolutely no idea what a leftist is.
Religionists never think their religion is wrong. But I don't belong to your cult.

Leftists never have any idea what a leftist is. But I don't belong to your cult.
