Growth Alone Doesn’t Drive Wellbeing
Global GDP has tripled since 1970, yet life satisfaction in wealthy nations has not increased. This disconnect—the Easterlin paradox—reflects a robust empirical pattern: wellbeing rises with income but with sharply diminishing returns. Early income gains secure basic capabilities; later gains increasingly fund status competition, complexity and defensive spending. Here we show that what matters for national wellbeing is not how much an economy spends, but how it allocates that spending.
Across 30 countries, we decompose system overhead into Institutional Infrastructure (universal systems, safety nets), Remediation Load (preventable disease, pollution, disasters) and Extractive Dissipation (rent-seeking, arms races). The share devoted to infrastructure—the Institutional Ratio—is strongly associated with life satisfaction (r = +0.80, P < 0.001) and trust (r = +0.90, P < 0.001), while total overhead shows no association (r = −0.18, not significant).
Given diminishing returns, we ask: how much wellbeing does a society achieve per income doubling? Finland achieves 19% higher efficiency than the United States despite lower GDP4,5—a gap explained by composition. These findings suggest that improving wellbeing within ecological limits requires redirecting economic activity toward institutional capacity rather than aggregate expansion.
