It is not short-term thinking. It is how we all think on a daily basis, even unconsciously, because it maximizes survival and reproduction, at least on evolutionary scales.

> The group that maximizes their long-term reproduction is the one that inherits the earth.

Yes, that's an interesting paradox in a world where the poorer tend to have more (surviving) children that the richer. But it emerged only very recently on evolutionary scales.

Before it meant the group that even sometimes risked their life for the children of everyone in the tribe. I think you're discounting natural human altruism, which is well studied.

The tribe was bound by blood and reciprocal ties. This works at small scales, which is the context we evolved in.

This is why in a village where everyone knows each other people help each other but in a holiday resort locals screw tourists.

		Religions like Christianity are the natural development at global scale for that. We're losing that scaling in altruism now, but it doesn't have to be this way.

On a longer time scale, the poor having more children than the rich is a minor temporary aberration. Their fertility is going the same direction, just with a bit of a lag.
