The Bigger Picture
Zooming out from individual life stages: what does a welfare state actually do to inequality, poverty, and the economy's appetite for risk?
Inequality & poverty
The Gini coefficient is the standard way economists measure income inequality within a country. It boils down the entire income distribution to a single number from 0 to 100: 0 would mean everyone earns exactly the same, and 100 would mean one person earns all the income while everyone else earns nothing. No real country sits at either extreme — most developed economies fall somewhere between the mid-20s and mid-40s. The higher the number, the more income is concentrated toward the top of the distribution rather than spread evenly across the population.
Gini coefficient & child poverty rate
Gini: 0 = perfect equality, 100 = maximum inequality. Child poverty: OECD relative poverty measure, share of children below 50% of median income.
For comparison, the US's own official poverty rate (a different, absolute measure) was 10.6% in 2024, and its Supplemental Poverty Measure — which accounts for cost of living and benefits — was 12.9%.
Wealth at the top
A more redistributive tax-and-benefit system doesn't eliminate concentrated wealth at the very top — it mainly changes outcomes for the broad middle and bottom of the income distribution, which is where the poverty and inequality gap actually shows up.
