Life expectancy rose only modestly between the Neolithic era of 8500 to 3500 BC and the Victorian era of 1850 to 1900.13 An American born in the late nineteenth century had an average life expectancy of around forty-five years, with a large share never making it past their first birthdays.14 Then something remarkable happened. In countries on the frontier of economic development, human health began to improve rapidly, education levels shot up, and standards of living began to grow and grow. Within a century, life expectancies had increased by two-thirds, average years of schooling had gone from single to double digits, and the productivity of workers and the pay they took home had doubled and doubled and then doubled again. With the United States leading the way, the rich world crossed a Great Divide—a divide separating centuries of slow growth, poor health, and anemic technical progress from one of hitherto undreamed-of material comfort and seemingly limitless economic potential. For the first time, rich countries experienced economic development that was both broad and deep, reaching all major segments of society and producing not just greater material comfort but also fundamental transformations in the health and life horizons of those it touched. As the French economist Thomas Piketty points out in his magisterial study of inequality, “It was not until the twentieth century that economic growth became a tangible, unmistakable reality for everyone.”15 The mixed economy was at the heart of this success—in the United States no less than in other Western nations. Capitalism played an essential role. But capitalism was not the new entrant on the economic stage. Effective governance was. Public health measures made cities engines of innovation rather than incubators of illness.16 The meteoric expansion of public education increased not only individual opportunity but also the economic potential of entire societies. Investments in science, higher education, and defense spearheaded breakthroughs in medicine, transportation, infrastructure, and technology. Overarching rules and institutions tamed and transformed unstable financial markets and turned boom-bust cycles into more manageable ups and downs. Protections against excessive insecurity and abject destitution encouraged the forward-looking investments and social integration that sustained growth required. At every level of society, the gains in health, education, income, and capacity were breathtaking. The mixed economy was a spectacularly positive-sum bargain: It redistributed power and resources, but as its impacts broadened and diffused, virtually everyone was made massively better off.
