Résumé de The Price of Inequality

In *The Price of Inequality*, Joseph E. Stiglitz argues that inequality in the United States is not merely an economic outcome but a cause of slower growth, political dysfunction, and diminished opportunity. Writing as a Nobel laureate economist and former World Bank chief economist, he contends that markets are not naturally efficient or fair; instead, political rules shape them, and those rules have increasingly been written by and for the wealthy. The book's central framework distinguishes between inequality of outcomes and inequality of opportunity, showing how the former undermines the latter, creating a vicious cycle that erodes social mobility and trust in institutions. Stiglitz develops this through several specific arguments. He describes "rent-seeking," where concentrated interests use political influence to capture disproportionate gains—through favorable tax treatment, subsidies, and deregulation—rather than creating new wealth. He points to the financial sector's role in the 2008 crisis, arguing that banks privatized gains while socializing losses, then used their political power to resist meaningful reform. He also examines how inequality weakens aggregate demand, since wealthy households spend a smaller share of their income, and how it distorts public investment in education, infrastructure, and health. The book critiques the notion of a pure meritocracy, noting that inheritance, social connections, and access to elite education perpetuate advantage across generations. Stiglitz proposes remedies such as progressive taxation, stronger labor protections, campaign finance reform, and greater public investment, framing these not as charity but as necessary for sustainable prosperity. He warns that persistent inequality threatens democratic governance itself, making the book both an economic analysis and a political argument about the costs of allowing concentrated wealth to shape collective decisions.
