THE FEW HAVE TAKEN
MOST OF IT.
The top 1% of adults globally hold roughly 38% of household wealth (World Inequality Database 2024). The world's ~2,800 billionaires control about $14 trillion (Forbes 2024), more than every country's GDP except the US and China. The top 1% of emitters produce more CO₂ than the bottom two-thirds of humanity (Oxfam & SEI 2023). Where this shows up is São Paulo, Riyadh, Berlin, and San Francisco, and the shape is different in each.
Six figures behind the composite.
One 0-100 score.
Heuristic seed snapshot. Inequality stress sits in the upper half of the 'Severe' band: top-1% wealth shares at multi-decade highs, billionaire wealth gains during the pandemic and inflation period that vastly outpaced wage growth, US CEO-to-worker pay ratio near 290:1, and a measurable transmission from wealth concentration to political outcomes. The carbon-inequality signal links the pillar directly to the climate pillar: the top 1% of emitters generate as much CO₂ as the bottom two-thirds of humanity.
Over time.
Six measures, fifteen economies.

The richest 1% pollute more than the poorest 66%.
Oxfam & Stockholm Environment Institute, Confronting Carbon Inequality 2023. Top-1% emitters generate ~16% of global CO₂; bottom-50% just 12%. The link between this pillar and the climate pillar is causal, quantified, and stable across the data.
The US case in two time-series, and why it is the leading global signal.
Top-1% wealth share, six decades.
Post-war compression unwound, then more so. Trough in the late 1970s; the climb back resumes through every decade since, with the 2020 capital-gains windfall adding another step. The European U-shape is shallower; the Asian curve looks different again. The US is the textbook case.
S&P 500 CEO-to-typical-worker pay ratio.
EPI methodology. The 1965 baseline of 21:1 is roughly where Japan still sits (15:1). France and the UK never crossed 200:1; the US sits near 290:1 even after the post-bubble normalisation.
What the score is measuring.
Several traditions reading the same data.
Why has wealth concentrated so heavily, and is concentration itself the problem?
When the rate of return on capital (r) systematically exceeds the rate of growth (g), inherited wealth grows faster than earned income and concentration becomes structural. Post-1980 policy choices (deregulation, financialisation, weakened unions, lower top tax rates) reinforced that gap. Concentration itself is the political problem; it converts into capture.
“When the rate of return on capital significantly exceeds the growth rate of the economy, capitalism automatically generates arbitrary and unsustainable inequalities.”
Differences in income and wealth largely reflect differences in productivity, risk-taking, and human capital. Some level of inequality is a price worth paying for the dynamism it incentivises; redistribution beyond a modest level damages growth and ultimately the people it tries to help. The poverty line, not the gap, is what matters.
“A society that puts equality before freedom will get neither. A society that puts freedom before equality will get a high degree of both.”
Capital accumulation is structural exploitation of labour, not the reward for productivity. The wage-profit relation determines how the surplus is split, and capital's structural power means it almost always wins. Reform alone cannot fix the relation; the alternative is to socialise the means of production, in whatever form a given context permits.
Inequality is the natural and morally legitimate outcome of voluntary exchange among free people. As long as the rules of acquisition are just, the resulting distribution is just regardless of how unequal it looks. Redistribution requires coercion and substitutes someone's preferred end-state pattern for the freely-arrived-at one.
Both traditions treat extreme wealth as a moral and spiritual hazard. Catholic social teaching frames property as having a universal destination; Islamic economics frames wealth as a trust on which annual zakat is due. Both reject unconditional libertarianism and unconditional state ownership; both insist on duties of the rich to the poor that the state may but need not enforce.
“We can no longer trust in the unseen forces and the invisible hand of the market.”
Pre-state and many continuing Indigenous economies were not subsistence economies that grudgingly redistributed; they were redistribution-first economies. Potlatch, kula, ubuntu, takhar all treat wealth-hoarding as anti-social. The contemporary 'rediscovery' of universal basic services or commons-stewardship has direct parallels in living traditions.
Of the interventions on the table, which move the needle and which are wishful?
The most-evidenced interventions: raise effective rates at the top via wealth and inheritance taxes (Saez/Zucman), close offshore loopholes (Zucman global minimum), expand earned-income credits at the bottom. Implementation is the bottleneck, not design.
Redistribution after the fact is politically fragile. The bigger lever is the pre-tax distribution itself: collective bargaining, union density, sectoral wage boards, minimum-wage architecture, public-option provision. Restore the labour-vs-capital balance and post-tax outcomes follow.
Universal basic income (cash) and universal basic services (housing, healthcare, transit, childcare) attack the precarity floor directly. Trials in Kenya, Finland, Stockton show mixed but generally positive results on wellbeing, weak negative results on labour-supply.
If the issue is who owns capital, expand who owns capital. Mondragón, John Lewis Partnership, ESOPs in the US. Empirical evidence is mixed on macro-effects but consistent on within-firm outcomes (lower inequality, higher resilience).
Within-country inequality is a real concern but the bigger moral target is between-country inequality. Dollars deployed in low-income contexts (GiveDirectly, deworming, vaccines) buy far more wellbeing per dollar than within-rich-country interventions. The implication for action is that effective philanthropy and global redistribution dwarf domestic policy.

How this pillar is scored.
Methodology & limits
Ten signals, weighted into a 0-100 score. Structural signals (top-1% share, labour vs capital share) move once a year. Faster signals (lobbying flows, capture indices, billionaire wealth) update more often.
Wealth-to-political-voice gets a heavy weight on purpose. Gilens & Page found that, once you control for top-decile preferences, median-voter preferences have close to zero independent effect on US federal policy. That's the moment inequality stops being just an economic measurement and starts being a political one.
Carbon inequality is a signal here because emissions concentrate where wealth does. That makes climate policy partly an inequality policy, and the reverse. The link is in the data, not just the framing.
Cross-country comparisons follow World Inequality Database conventions where possible, harmonised to the latest reference year. CEO-pay ratios and mobility figures don't have a single global methodology; in those cases the most-cited national source is used and noted on the chart.
