Tim Jackson is the ecological economist best known for Prosperity Without Growth, and Post Growth is the more personal, more literary sequel to it. Where the earlier book made the technical case that rich economies cannot decouple GDP from material throughput fast enough to hit climate targets, this one steps back and asks a prior question: what was growth ever supposed to be for? The book proceeds less as an argument than as a series of portraits — each chapter built around a figure whose life illuminates some part of the answer, among them John Stuart Mill, Robert Kennedy, Lynn Margulis, Hannah Arendt, Emily Dickinson, Rosa Luxemburg and Thich Nhat Hanh. It is economics written in the register of an essay.
The core argument
Jackson’s claim is that growth has been mistaken for prosperity, and that the substitution has cost us the thing itself. Endless expansion of output is physically impossible on a finite planet, and — this is the part that distinguishes him from a purely ecological argument — it is not even delivering what it promises in the countries that have most of it. Beyond a certain point, additional GDP buys little additional health, security, meaning or life satisfaction, while the pursuit of it corrodes the relationships and the natural systems on which real wellbeing rests.
His alternative is not austerity. Prosperity, he argues, is the capacity to flourish as human beings: health, purpose, connection, participation, time. Much of what supplies it — care, craft, teaching, community — is labour-intensive by nature and therefore looks like a productivity problem to conventional economics. Jackson inverts this. The sectors where productivity growth is hardest are precisely the ones a post-growth economy should expand, because their inefficiency is the point: the value is in the time spent with the person.
Key ideas
- The myth of growth. Jackson traces how GDP, designed as a wartime accounting device, became a national purpose, and revisits Robert Kennedy’s 1968 verdict that it measures everything except what makes life worthwhile.
- The limited and the limitless. Material throughput is bounded; human creativity, care and meaning are not. The confusion between the two is the century’s central category error.
- Capitalism died of its own contradictions. Financialisation, secular stagnation and the collapse of productivity growth suggest the growth engine is already failing on its own terms, whatever we decide about it.
- Love and entropy. Against the thermodynamic pull toward disorder, life persists by building structure. Drawing on Lynn Margulis, Jackson argues that symbiosis and cooperation, not competition, are biology’s dominant motif — and should be economics’ too.
- Work as contribution, not just income. The point of labour is participation in something shared; an economy of care and craft rehabilitates work rather than abolishing it.
- Economics as storytelling. Models are narratives, and the narrative of the rational maximiser has been performative — teaching it made people behave more like it.
Who it’s for
Read this if you want the philosophical and moral case for degrowth rather than the technical one, and if you enjoy books that move between economics, biology, poetry and biography without apologising. Jackson writes beautifully and the portrait structure gives the material real emotional weight — the pandemic-era closing chapter on Venice’s clear canals lands harder than a chart would. The fair criticism is that it is stronger on vision than on mechanism: readers who want to know how a wealthy democracy actually transitions off growth — what happens to debt, pensions, employment and political consent along the way — will find those questions acknowledged more than answered. For that, Prosperity Without Growth is the better companion. This book is the one that tells you why it would be worth the trouble.
