A century ago, industrialists like Andrew Carnegie believed that Darwin’s theories justified an economy of vicious competition and inequality. They left us with an ideological legacy that says the corporate economy, in which wealth concentrates in the hands of a few, produces the best for humanity. This was always a distortion of Darwin’s ideas. His 1871 book The Descent of Man argued that the human species had succeeded because of traits like sharing and compassion. “Those communities,” he wrote, “which included the greatest number of the most sympathetic members would flourish best, and rear the greatest number of offspring.” Darwin was no economist, but wealth-sharing and cooperation have always looked more consistent with his observations about human survival than the elitism and hierarchy that dominates contemporary corporate life.
