“Gaus acknowledges that Late Pleistocene (LPA) hunter-gather societies engaged in egalitarian meat-sharing. That was a means of reducing the variance in food intake, but it also reflects successful efforts by subordinates to control would-be bullies and upstarts. Under that interpretation, the egalitarian ethos of LPA societies was not inherently collectivist. LPA societies ‘appear characterized by a near-obsession with resisting the authority of would-be dominators.’ LPA societies also exerted immense social pressure against innovators who sought to introduce new techniques to improve their own lot. This may have been an effective way to protect distributive shares. People in LPA societies had a strong ethic of reciprocation – they engaged in the conditional cooperation that enables markets to function. Social support was more readily available to those who had a reputation for being willing to assist others.” (10/30/25)
