Summary: Recent debates have framed global inequality as rapidly worsening, particularly in response to the COVID-19 pandemic. Evidence from the Inequality of Human Progress Index indicates that, despite temporary setbacks, long-term declines in inequality across multiple dimensions of wellbeing have largely persisted, with global disparities remaining well below 1990s levels.

Affordability fears, talk of a “K-shaped” economy, and claims of a new Gilded Age have pushed inequality to the center of today’s policy debates. Calls for a worldwide wealth tax and other unprecedented measures are not treated as radical but as inevitable—across academia, non-profits, the press, and international organizations, including the United Nations.

The COVID-19 pandemic seemed to clinch the case. As economies contracted and progress in poorer countries stalled, it was easy to assume that decades of convergence between developed and developing countries had come to an end. The authors of one Oxfam paper, for example, proclaimed during the pandemic that “unparalleled action [is] needed to combat unprecedented inequality in the wake of COVID-19.”

New research suggests a more nuanced reality. The updated Inequality of Human Progress Index assesses how the pandemic affected progress toward a more prosperous and equal world.

The pandemic clearly slowed improvement in global living standards and interrupted the pace at which countries were becoming more equal. It did not, however, cancel out the long-term, positive trends. Even under the strain of COVID-19, its attendant lockdowns, and other forceful policy responses, global inequality across key measures of well-being remained lower than it was a generation ago.

The index looks beyond income alone. It measures inequality across eight dimensions that shape everyday life, including lifespan, child survival, nutrition, education, internet access, environmental safety, income, and political freedom. The index, which I co-authored with George Mason University economist Vincent Geloso, seeks to offer a fuller view of gaps in global development, taking into account more aspects of human well-being than any prior index of inequality.

The data show a substantial decline in global inequality over the past three decades as rising prosperity allowed poor countries to narrow gaps with rich ones. That pattern held through 2019. During the pandemic years of 2020 and 2021, progress slowed sharply and, in some areas, stalled or modestly reversed. Yet the earlier gains were not erased.

This distinction is important. COVID-19 was a severe shock. Life expectancy fell worldwide. School closures disrupted education. Economic activity and international trade declined, with especially devastating effects on low-income countries. The index reflects these setbacks. Inequality stopped falling at its earlier pace and, in some measures, edged upward slightly after years of progress. Still, the overall level of global inequality remained far below where it stood in the 1990s.

In a few areas, improvement continued even during the crisis. Internet access expanded rapidly, especially in poorer countries, reducing inequality in access to information to its lowest level on record. Faster regulatory approvals amid the pandemic helped bring more people online. In Kenya, for example, Alphabet’s high-altitude internet balloons were finally cleared in 2020, allowing rural areas to gain internet access for the first time. The project had been stalled in regulatory review for nearly two years before the crisis prompted action.

Not all the data were encouraging. Inequality in political liberty ticked up during the pandemic as many countries took a turn toward greater authoritarianism. Even with the long-term shift toward electoral democracy intact, the setback shows the importance of protecting political liberty during emergencies.

For all the turmoil, the damage across different measures of well-being was thankfully limited.

These findings complicate popular claims that the world is experiencing a runaway increase in inequality. Calls for a global wealth tax, massive new aid commitments, or other significant expansions of state redistribution often rest on the premise that trade and free enterprise have failed to deliver shared gains. The data suggest otherwise.

If anything, the pandemic highlighted how sensitive progress can be to disruptions in markets. Countries with greater economic freedom generally proved more resilient. In contrast, prolonged lockdowns and restrictions often imposed heavy costs on poorer populations, particularly in countries where remote work and online schooling were not viable options for most people.

The broader lesson is that global convergence is neither automatic nor guaranteed, but instead depends on certain conditions such as undisturbed markets, even as long-term progress has proven more robust than critics often assume.

Mistaken narratives about global inequality have real consequences. They shape public opinion and influence policymakers to embrace sweeping interventions. A more accurate assessment of recent history suggests a need for caution.

COVID-19 tested the global economy in ways few events in modern history have. It slowed human progress and exposed vulnerabilities. At the same time, it demonstrated the durability of the long-term trend toward lower global inequality. Preserving and strengthening the policies and institutions that made that progress possible, including economic and political freedoms, remains a better bet than assuming they have already failed. The gains of recent decades have left the world both better off and more equal.

“Whether each generation of Americans continues to economically surpass the previous one has recently been called into question. We construct a posttax, posttransfer income measure from 1963 to 2023 based on the Current Population Survey Annual Social and Economic Supplement that allows us to consistently compare the economic well-being of five generations of Americans at ages 36–40. We find that Millennials had a real median household income that was 20% higher than that of the previous generation, a slowdown from the growth rate of the Silent Generation (36%) and Baby Boomers (26%), but similar to that of Generation X (16%). The slowdown for younger generations largely resulted from stalled growth in work hours among women. Progress for Millennials younger than 30 has also remained robust, though largely due to greater reliance on their parents. Additionally, lifetime income gains for younger generations far outweigh their higher educational costs.”

From Demography.

Summary: Widespread claims of rapidly worsening global inequality are unsupported by the evidence. Long-term data show significant declines in inequality across income, health, education, and other important metrics, largely driven by rising prosperity in poorer countries. Popular policy proposals to address inequality, such as wealth taxes and expanded foreign aid, are misguided and dangerous. Policies that sustain economic growth and market stability are better guarantors of progress.

Anthropic CEO Dario Amodei called for far higher taxation in a recent blog entry, arguing that current wealth concentration is higher than that of the Gilded Age and is about to get worse globally. The chart-topping singer Billie Eilish implored billionaires to give away their money, while New York City mayor Zohran Mamdani has gone further, opining, “I don’t think we should have billionaires” because we live in “a moment of such inequality.” If anything is having a moment, it is the conviction that inequality has grown urgent enough to justify a muscular policy response.

But the facts don’t support this. Not only has global income inequality fallen over the long run — contrary to the popular narrative — but inequality has also declined in education, health, and a host of other areas. The world is now more equal across a range of factors, from lifespan and childhood survival to internet access and schooling. The more broadly one examines inequality, the more encouraging the data appear. It turns out that even the shock of COVID-19 failed to erase decades of progress toward a wealthier and more equal world.

Indeed, the data show a pronounced decline in global inequality over the past few decades, driven largely by rising prosperity in poorer countries. During the pandemic years of 2020 and 2021, progress slowed sharply. Some indicators stalled and a few modestly worsened. But the gains accumulated before the crisis were not undone.

In short, the damage to human well-being was more limited than many feared. 

Another recent analysis published in The Economist finds that global inequality in consumption spending is falling. In 2000, the richest 10% of humanity spent 40 times more than the poorest 50%. In 2025, they spent around 18 times more. Using data from World Data Lab, they find that the poorest 50% now out-consume the richest 1%, breaking from past trends.

Yet many think that only large-scale redistribution can stop runaway worldwide inequality. Figures as diverse as Amodei, Eilish, and Mamdani are far from alone in embracing this view. Over the past few years, calls for a worldwide wealth tax, a vast increase in foreign aid spending, and other unprecedented measures are gaining steam across academia, non-profits, the press, and international organizations like the United Nations. 

That conclusion is premature. Getting the facts straight is essential, because misunderstanding global inequality can push policymakers toward harmful solutions.

The record on foreign aid is far less encouraging than its advocates suggest: decades of evidence show that aid frequently fails to deliver sustained development and bears no reliable relationship to long-term economic growth. Worse, the fixation on ever larger aid flows often crowds out the harder work of domestic reform. In some cases, foreign aid has been shown to weaken political institutions, entrench bad governance, and slow the process of democratization.

Wealth taxes have their own problems, from high administrative costs and enforcement challenges to low revenue production and invasion of financial privacy. These problems help explain why so many of the countries that have implemented wealth taxes in the past — such as France, Germany, and Sweden— later abolished the tax. Perhaps the worst of all, by discouraging risk-taking, wealth taxes suppress investment and growth, effects that would be felt in both rich and poor countries and would likely prove especially damaging to development in the world’s poorest economies.

Recent work on multidimensional inequality suggests that the world has not been drifting toward ever greater gaps, but that the rich and the poor have been converging in material comfort. Calls for global wealth taxes or massive new aid programs often rest on the assumption that international trade and economic freedom have failed to deliver broadly shared gains. Yet the long-term evidence suggests the opposite.

The pandemic offers two lessons here: First, it highlights just how sensitive progress is to disruptions in markets. It depends on conditions that allow growth to occur and persist, including functioning markets and stable institutions. Many of the proposed policy solutions risk undermining that progress.

The second lesson is that while the pandemic represented a hurdle in the path of progress, the long-term trend toward lower global inequality is holding strong.

Alarmist narratives shape public opinion and encourage policymakers to pursue sweeping interventions that may do more harm than good. A clearer view of the data counsels caution rather than panic.

We are excited to share a new tool we’ve been building at Human Progress: The American Abundance Index—an interactive dashboard that tracks US living standards while adjusting for both inflation and rising incomes.

The idea is straightforward: how many hours do you need to work to afford the same basket of goods and services? Using Bureau of Labor Statistics data, the American Abundance Index converts price and wage growth into “time prices”—the amount of work time required to buy the Consumer Price Index (CPI) basket of goods and services—and “abundance,” which is the inverse: how much of that basket one hour of work can buy. When time prices fall, abundance rises, and each hour of work goes further. That’s the measure of affordability that actually matters.

Conceptually, this work builds off of Superabundance, a book by our editor, Marian Tupy, and his coauthor and Human Progress board member, Gale Pooley. Their core argument—that abundance is best measured in time—forms the foundation of the project. The index itself was built by our Quantitative Research Associate, Jackson Vann.

Users can select multiple worker categories, compare short- and long-run trends, and even see wage growth modeled to reflect real career progression rather than freezing workers in place. All the calculations are transparent and replicable, with the full dataset and code available on GitHub.

So what does the index actually say about American standards of living?

Over the past 12 months, inflation rose 2.68 percent while hourly earnings for the average private-sector worker grew 3.76 percent. As a result, the CPI basket became 1.05 percent more abundant. Since 2006, it has become nearly 14 percent more abundant—roughly equivalent to adding an hour of purchasing power to the average workday.
