Recent debates surrounding the concept of degrowth—a call to intentionally slow or reverse economic growth to achieve environmental sustainability and social equity—have gained renewed attention following the publication of the Global Justice Report by French economist Thomas Piketty and his colleagues. The report advocates drastically curbing annual per capita economic growth in Western countries to between 0 and 0.5 percent as a core strategy for addressing inequality and environmental concerns. Nobel laureate Joseph Stiglitz and others have also voiced skepticism about the viability of growth as a sustainable strategy.
While acknowledging the report’s emphasis on the destabilizing effects of extreme inequality and the importance of sustainable development, recent research challenges several key assumptions underpinning the degrowth argument. Historically, economic growth was closely linked to rising pollution and environmental degradation. However, data from high-income countries between 1960 and 2022 indicate that this link has weakened significantly. Many developed economies are now achieving GDP growth while simultaneously reducing per capita emissions of carbon dioxide, sulfur dioxide, and material consumption, in part due to stringent regulations and technological innovations such as the expansion of solar power and battery storage.
Furthermore, the relationship between economic growth and social outcomes may be more closely aligned than some degrowth proponents suggest. Long-term economic studies show a persistent correlation between increases in GDP per capita and reductions in poverty levels across diverse global regions and historical periods. Updated analyses incorporating data from the last 15 years suggest that when incomes for the poorest segments stagnate, it often coincides with periods of limited overall economic growth rather than uneven wealth distribution.
Claims that wage growth has decoupled from rising productivity in advanced economies are also contested. When making consistent comparisons, worker compensation and output have generally moved in parallel across both sides of the Atlantic. Moreover, recent research challenging the notion that well-being plateaus in affluent nations highlights that life satisfaction continues to improve alongside GDP per capita, once adjustments are made for changing individual expectations over time.
Beyond individual economic indicators, growth appears to have broader societal benefits. Studies suggest that growing prosperity can reinforce trust in government and enhance social cohesion. For example, while the United Kingdom has experienced a decade of political turbulence, this period coincided with slow economic growth rather than increased income inequality, which has reportedly declined.
Nevertheless, analysts acknowledge that the current economic system remains imperfect and faces future challenges, including the potential for artificial intelligence to disproportionately benefit capital owners over workers, which could exacerbate inequality. Concerns also persist about the potential social and political consequences of slowing growth—whether due to demographic trends, policy decisions, or explicit degrowth strategies—including stagnating living standards and heightened intergroup competition for resources.
In summary, recent evidence indicates that economic growth in many rich countries need not come at the expense of environmental objectives or poverty reduction. While growth alone is not a panacea, it continues to play a central role in advancing multiple social and environmental goals. The ongoing debate about degrowth highlights the complexity of balancing prosperity, equity, and sustainability in a changing world.
