The Broken Ladder: Capitalism, Mobility, and Inequality

Introduction: Testing Capitalism's Promise

Few economic debates carry more moral weight than the question of whether capitalism, for all its celebrated dynamism, ultimately delivers on its promise of opportunity. Defenders of the market system point to entrepreneurs who rose from poverty to prominence, to nations that lifted millions out of destitution through market-led growth, and to the sheer volume of goods and services that capitalism generates. Critics respond with statistics on wealth concentration, stagnant wages, and the stubborn persistence of class across generations. Both camps engage with real evidence. But engaging with the strongest version of both positions leads to an uncomfortable conclusion: capitalism's contributions to individual success, while genuine, do not outweigh the structural inequalities it entrenches, because the data on social mobility, wealth concentration, and access to entrepreneurship reveal that market systems systematically reward those who begin with advantages while narrowing the path for those who do not.

Social Mobility and the Geography of Opportunity

This is not an argument against markets per se, nor a call for their abolition. It is an argument that the ideological story capitalism tells about itself—that effort and ingenuity reliably translate into success regardless of starting point—diverges sharply from the empirical record. Understanding that divergence matters because policy choices that assume meritocratic markets will naturally correct for inequality consistently fail the people they claim to serve.

The most direct way to test capitalism's promise of individual success is to examine social mobility—the degree to which a person's economic outcome depends on talent and effort rather than family background. The results are sobering. Economist Raj Chetty and his colleagues at the Equality of Opportunity Project produced some of the most comprehensive mobility research ever conducted on the United States, tracking millions of Americans across generations. Their findings showed that a child born in the bottom income quintile has roughly an 8 percent chance of reaching the top quintile—a figure that has barely changed in decades and that compares unfavorably to several European social democracies where markets are also central but where redistributive policy is more robust (Chetty et al. 2309). The American Dream, in other words, is statistically more achievable in Denmark or Canada than in the country that invented the phrase. This is not a peripheral finding. It strikes at the core claim that capitalism rewards individual potential.
