The Philosophy of Growth: Should Economies Always Grow?

Why economic growth is treated as a default good, and the arguments of thinkers who question that assumption.

Economic growth is treated, in most political and economic discussion, as an obviously good thing that policymakers should pursue whenever possible. But a smaller, persistent tradition of economic and philosophical thought has questioned whether growth should really be treated as an unquestioned goal, and their arguments are worth taking seriously even if you end up disagreeing with them.

Why growth became the default goal

GDP growth - the increase, over time, in a country’s gross domestic product, the total market value of goods and services produced within its borders - became a central policy target through much of the twentieth century, largely because it correlates strongly with many things people clearly value: rising incomes, more jobs, greater tax revenue for public services, and generally more resources available to address other social problems. A growing economy also tends to make it politically easier to redistribute gains without asking anyone to accept a shrinking slice of the pie, since even a smaller relative share of a larger total can still mean an absolute increase.

The case for questioning growth

Critics of treating growth as an unquestioned goal raise several distinct concerns. One is environmental: producing and consuming more goods and services generally requires more resources and energy, and can generate more pollution and environmental degradation, some of which may not be reflected in market prices at all. Economists call an unpriced cost like this an externality, a cost of an activity that falls on people or the environment outside the transaction that caused it - and critics argue that a strong focus on growth can encourage ignoring externalities that don’t show up in standard growth measurements.

A river that doesn't appear in the numbers

Imagine a factory that increases its production significantly, boosting the local economy's measured output and creating new jobs - a clear win by GDP growth measures. But suppose the factory's expanded production also releases pollutants into a nearby river, harming fish populations that a downstream community has fished for generations. GDP growth captures the added economic activity from the factory but does not directly subtract the value lost to the downstream community's damaged fishery, unless that harm happens to show up in some other measured transaction. Critics of growth-focused thinking argue this kind of gap between measured growth and actual well-being is common and consequential, not a rare exception.

Degrowth and steady-state alternatives

Degrowth is a school of thought arguing that wealthy economies should deliberately scale back overall production and consumption, particularly in resource-intensive sectors, prioritizing ecological sustainability and well-being over continued expansion of output. A related but distinct idea is the steady-state economy, a proposed model in which an economy maintains a roughly constant level of resource use and population over time, rather than pursuing continuous growth, drawing on the observation that infinite growth may be difficult to sustain within a finite set of natural resources.

Assuming degrowth means poverty or economic collapse

A common misunderstanding treats degrowth as simply advocating for poverty, unemployment, or economic ruin. Most degrowth thinkers explicitly distinguish their proposal from a recession, which is an unplanned, often painful contraction accompanied by rising unemployment and falling living standards. Degrowth instead proposes a deliberate, managed reduction focused specifically on resource-intensive and less essential production, paired with policies intended to maintain or improve well-being and reduce inequality even as overall material throughput declines - whether such a transition is actually achievable without significant hardship remains a genuinely contested empirical and political question.

A genuinely open debate

Most mainstream economists remain skeptical that degrowth or steady-state approaches are necessary or desirable, arguing that technological innovation, better pricing of externalities, and more efficient resource use can allow continued growth alongside environmental improvement - a view sometimes called decoupling. Whether growth can be sufficiently decoupled from environmental harm at the scale and speed required is itself a contested empirical question, not a settled one. This debate ultimately touches the same philosophical questions raised elsewhere in this module, particularly around Amartya Sen’s capability approach: should economic success be measured by output and growth, or by broader measures of human and ecological well-being that growth does not fully capture?

Key takeaways

GDP growth is treated as a default policy goal because it correlates with rising incomes and living standards.
Critics argue growth measurements often ignore externalities like environmental harm.
Degrowth advocates deliberately scaling back resource-intensive production, distinct from an unplanned recession.
A steady-state economy proposes maintaining roughly constant resource use rather than pursuing continuous growth.
Most mainstream economists favor decoupling growth from environmental harm rather than abandoning growth.
Whether decoupling is achievable at the needed scale remains a genuinely contested, unsettled question.
