The second crucial point of convergence was far more recent, and arguably far more transformative. It began some 12,000 years ago when some of our ancestors began to routinely store food and experiment with cultivation, transforming their relationships with their environments, with each other, with scarcity, and with work. Exploring this point of convergence also reveals how much of the formal economic architecture around which we organize our working lives today had its origins in farming and how intimately our ideas about equality and status are bound into our attitudes to work.

As farming societies grew more productive and captured more energy from their environments, energy appeared to be scarcer and people had to work harder to meet their basic needs. This was because, up until the Industrial Revolution, any gains in productivity farming peoples generated as a result of working harder, adopting new technologies, techniques, or crops, or acquiring new land were always soon gobbled up by populations that quickly grew to numbers that could not be sustained. As a result, while agricultural societies continued to expand, prosperity was usually only ever fleeting, and scarcity evolved from an occasional inconvenience that foragers stoically endured every once in a while to a near perennial problem. In many respects, the hundreds of generations of farmers who lived before the fossil-fuel revolution paid for our extended lifespans and expanded waistlines now by enduring lives that were mostly shorter, bleaker, and harder than ours, and almost certainly tougher than those of their foraging ancestors.

But there was more to the relationship between time and work in early agricultural societies than the tedious reality of being tied to an inflexible seasonal cycle. One of the most profound legacies of the transition to farming was to transform the way people experienced and understood time.

To foragers, change was immanent in the environment—it happened all the time, when the wind blew, the rain fell, or an elephant cleared a new path. But change was always constrained by a deeper sense of confidence in the continuity and predictability of the world around them. Every season was different from those that preceded it, yet these differences always fell within a range of predictable changes. Thus for the Ju/’hoansi, when they were still free to forage as their ancestors had, carrying the weight of history was as inconvenient as carrying a house around, and abandoning the deep past freed them to engage with the world around them unencumbered by ancient precedents or future ambitions.

Foragers like the Ju/’hoansi remind us that we are as capable of ordering ourselves into fiercely egalitarian societies as we are of ordering ourselves into rigid hierarchies. As a result, many historians have argued that even if inequality is not a brute fact of human nature, then along with zoonotic diseases, despotism, and war, it was probably a direct and immediate consequence of our embrace of agriculture. They reason that as soon as people had big surpluses to hoard, exchange, or distribute, the more miserable angels of our nature took over.
