@northernlights @Radical_EgoCom I'll put it on my reading list, but chances are I won't get to it this century. Sigh. Sounds similar to an Against The Grain book I have read. Its theory was that agriculture led to centralization because farmers are easier to conquer, they're tied to the land. Plus, primal civilization probably crashed several times and this was basically a good thing, survivors escaped to the hills.
@northernlights @Radical_EgoCom It would be sad if "adjust your oxygen mask before helping others" would increase inequality and reduce solidarity, but I suppose it makes sense it would.
