It’s said that nothing lasts forever…

In 1930, the English economist John Maynard Keynes took a break from writing about the problems of the interwar economy and indulged in a bit of futurology. In an essay entitled “Economic Possibilities for Our Grandchildren,” he speculated that by the year 2030 capital investment and technological progress would have raised living standards as much as eightfold, creating a society so rich that people would work as little as fifteen hours a week, devoting the rest of their time to leisure and other “non-economic purposes.” As striving for greater affluence faded, he predicted, “the love of money as a possession . . . will be recognized for what it is, a somewhat disgusting morbidity.”

This transformation hasn’t taken place yet, and most economic policymakers remain committed to maximizing the rate of economic growth. But Keynes’s predictions weren’t entirely off base. After a century in which G.D.P. per person has gone up more than sixfold in the United States, a vigorous debate has arisen about the feasibility and wisdom of creating and consuming ever more stuff, year after year. On the left, increasing alarm about climate change and other environmental threats has given birth to the “degrowth” movement, which calls on advanced countries to embrace zero or even negative G.D.P. growth. “The faster we produce and consume goods, the more we damage the environment,” Giorgos Kallis, an ecological economist at the Autonomous University of Barcelona, writes in his manifesto, “Degrowth.” “There is no way to both have your cake and eat it, here. If humanity is not to destroy the planet’s life support systems, the global economy should slow down.” In “Growth: From Microorganisms to Megacities,” Vaclav Smil, a Czech-Canadian environmental scientist, complains that economists haven’t grasped “the synergistic functioning of civilization and the biosphere,” yet they “maintain a monopoly on supplying their physically impossible narratives of continuing growth that guide decisions made by national governments and companies.”

Once confined to the margins, the ecological critique of economic growth has gained widespread attention. At a United Nations climate-change summit in September, the teen-age Swedish environmental activist Greta Thunberg declared, “We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!” The degrowth movement has its own academic journals and conferences. Some of its adherents favor dismantling the entirety of global capitalism, not just the fossil-fuel industry. Others envisage “post-growth capitalism,” in which production for profit would continue, but the economy would be reorganized along very different lines. In the influential book “Prosperity Without Growth: Foundations for the Economy of Tomorrow,” Tim Jackson, a professor of sustainable development at the University of Surrey, in England, calls on Western countries to shift their economies from mass-market production to local services—such as nursing, teaching, and handicrafts—that could be less resource-intensive. Jackson doesn’t underestimate the scale of the changes, in social values as well as in production patterns, that such a transformation would entail, but he sounds an optimistic note: “People can flourish without endlessly accumulating more stuff. Another world is possible.”

Even within mainstream economics, the growth orthodoxy is being challenged, and not merely because of a heightened awareness of environmental perils. In “Good Economics for Hard Times,” two winners of the 2019 Nobel Prize in Economics, Abhijit Banerjee and Esther Duflo, point out that a larger G.D.P. doesn’t necessarily mean a rise in human well-being—especially if it isn’t distributed equitably—and the pursuit of it can sometimes be counterproductive. “Nothing in either our theory or the data proves the highest G.D.P. per capita is generally desirable,” Banerjee and Duflo, a husband-and-wife team who teach at M.I.T., write…

As the estimable John Cassidy (@JohnCassidy) explains, the critique of economic growth, once a fringe position, is gaining widespread attention in the face of the climate crisis: “Can We Have Prosperity Without Growth?“

* “When the accumulation of wealth is no longer of high social importance, there will be great changes in the code of morals. We shall be able to rid ourselves of many of the pseudo-moral principles which have hag-ridden us for two hundred years, by which we have exalted some of the most distasteful of human qualities into the position of the highest virtues. We shall be able to afford to dare to assess the money-motive at its true value. The love of money as a possession — as distinguished from the love of money as a means to the enjoyments and realities of life — will be recognized for what it is, a somewhat disgusting morbidity, one of those semi-criminal, semi-pathological propensities which one hands over with a shudder to the specialists in mental disease.” — John Maynard Keynes, Economic Possibilities for Our Grandchildren

As we internalize externalities, we might send carefully-conserved birthday greetings to Gifford Pinchot; he was born on this date in 1865.  An American forester, he became the first chief of the Forest Service in 1905. By 1910, with President Theodore Roosevelt’s backing, he built 60 forest reserves covering 56 million acres into 150 national forests covering 172 million acres.  Roosevelt’s successor, President Taft– no environmentalist– fired Pinchot.  Still Pinchot’s efforts earned him the honorific, “the father of conservation.”
