ERROR: Postulation of group selection detected in paragraph 3.

Group seleciton indeed. Although I'm talking about both biological and cultural evolution working together, and in such a context, group selection is plausible (not that it's entirely implausible in biological evolution).

See Haidt & Kesebir (2009) for an overview of group selection in this context.

In short, it's not all about altruism but about group cohesion, and promoting group cohesion doesn't need to come at the same cost that accompanies altruism.
