I notice that some anthropologist believe all humans were egalitarian in the past, and others believe inequality was more common they we currently we think with hunter gathers.
This seems to along with anthropologist using modern hunter gathers as way to look at the past which is now considered not a best practice from what I read. Which this influenced the egalitarian hunter gathers idea even more.
An experiment involving introducing the game “musical chairs” to children attempted to answer this question. In addition to the normal version, an alternative version where everyone would share fewer and fewer chairs was played.
The children almost ubiquitously preferred the cooperative version.
