When we transitioned from the Forager Age to the Agrarian Age, we went from nomadic to sedentary, from egalitarian to hierarchical, from promiscuous to monogamous and from animistic to theistic religions. When we went from the Agrarian Age to the Industrial Age, we moved from the countryside to cities, from large extended families to nuclear ones, from commons to private property, and from great-chain-of-being theologies to the Protestant work ethic. Though the first of these transitions took place over millennia and the second one over centuries, they still show that a shift in the binding scarcity comes with profound changes in how we live.
