Which billionaire is trashing the planet? My claim is based on the following:
Over the last 100 years (roughly 1925โ2025), market-oriented economic systemsโcharacterized by free markets, capitalism, globalization, trade liberalization, property rights, and entrepreneurshipโhave been the primary driver behind the largest reduction in extreme poverty in human history.
Exact global figures for the full century are estimates (reliable household survey data starts around 1981 from the World Bank), but historical reconstructions and post-1950/1980 trends show dramatic progress coinciding with the spread of market economies, industrialization, and reforms (especially in East Asia after the 1970sโ80s).
Key Global Statistics
โข Early 20th century baseline: In 1820, ~84โ90% of the worldโs population lived in extreme poverty (less than ~$2.15/day in modern PPP terms). By 1910โ1950, this had declined to around 55โ72%, with slower progress amid wars and pre-liberalization economies.
โข Post-1950 acceleration: Around 1950, ~55โ60% of the global population was in extreme poverty. Strong economic growth in market-reforming countries drove major gains.
โข 1990โpresent (most rapid phase):
โข ~1.9โ2.3 billion people in extreme poverty in 1990.
โข Down to ~650โ800 million today (around 8โ10% of world population), despite global population growing from ~5.3 billion to ~8 billion.
โข This represents over 1 billion to 1.5 billion people lifted out of extreme poverty in roughly 35 years. On average, ~40โ50 million per year in peak periods.
Over the broader 20thโ21st century span, the net reduction is in the range of billions when accounting for population-adjusted escapes from poverty, with the bulk tied to market-driven growth.
Major Contributors (Market Reforms)
โข China: ~680โ800 million lifted since ~1981, after Deng Xiaopingโs market-oriented reforms (special economic zones, private enterprise, trade opening). Poverty rate fell from ~88% in 1981 to near 0%.
โข India and East/South Asia: Significant gains from liberalization in the 1990s onward (hundreds of millions more).
โข Broader developing world: Post-2000, another ~280 million outside China in earlier periods, driven by global trade, investment, and growth.
Economists often attribute this to economic freedom (property rights, low barriers to trade/enterprise, sound money), with indices from the Fraser Institute and Heritage Foundation showing strong correlations between higher freedom scores and faster poverty reduction, higher incomes (including for the poorest), and growth.
Important Context and Caveats
โข Not purely โfree marketsโ alone: Institutions, stable governance, education, health investments, and targeted policies played roles. Our World in Data notes that while markets and globalization were key, government revenues and transfers also helped. Chinaโs success blended market incentives with state direction.
โข Definition: Extreme poverty uses the World Bankโs International Poverty Line (~$2.15/day in 2017 PPP), a very low bar focused on basic survival needs. Higher lines (e.g., $6.85/day) show more persistent poverty.
โข Recent slowdown: Progress stalled post-COVID, with ~700 million still in extreme poverty as of recent estimates. Conflicts, fragility, and uneven growth are challenges.
โข Counter-views: Some critics argue pre-industrial poverty baselines are overstated or that gains reflect non-market factors (e.g., public health). However, the correlation with market liberalization periods is widely documented.
This represents unprecedented human progress: from near-universal extreme poverty centuries ago to most of humanity above it today, enabled by productive market economies generating wealth, innovation, and opportunity.
