The choice is not between hands-on or hands-off. In our research, the entrepreneurs who led their companies from start-ups into some of the greatest corporations in history generally had both a hands-on style and an empowering style. No matter how big their companies became, they remained closely connected to their people, hyper-aware of facts on the ground, and directly engaged in strategic imperatives. If you lose your voracious curiosity about tactical details, if you lose passionate interest in people and how they are feeling, if you insulate yourself in the protective cocoon of executive comforts, you may well wake up one day to discover your company has already entered a doom loop of decline and self-destruction.

Entrepreneurship, or what Nobel Prize–winning economist Edmund Phelps calls “grassroots innovation,” is as central to economic dynamism today as it was in the nineteenth century. Entrepreneurs unlock the value of new technologies, spur competition, satisfy unmet needs, and create new jobs.

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.

Over the course of the seventeenth and eighteenth centuries, the desire of poorer people in cities across Europe to consume what were once luxuries enjoyed only by the very rich was just as influential in shaping the history of work as the invention of technologies to exploit the energy in fossil fuels. Without it, there would have been no markets for mass-produced items, and without markets the factories would never have been built. It also rewrote the rules by which much of the economy operated. The growth of Britain’s economy increasingly came to depend on people employed in manufacturing and other industries reinvesting their wages in the very same products they and their factory workers manufactured.

The principal purpose, however, has been to loosen the claw-like grasp that scarcity economics has held over our working lives, and to diminish our corresponding and unsustainable preoccupation with economic growth. For by recognizing that many of the core assumptions that underwrite our economic institutions are an artifact of the agricultural revolution, amplified by our migration into cities, frees us to imagine a whole range of new, more sustainable possible futures for ourselves, and rise to the challenge of harnessing our restless energy, purposefulness, and creativity to shaping our destiny.
