A new report by the Congressional Budget Office (CBO) revealed a significant shift in the distribution of income in the United States between 1979 and 2022, indicating a decline in the economic standing of the middle class. The data showed a marked increase in the share of national income held by the wealthiest households, while the middle three income quintiles experienced a reduction in their share, even after accounting for government transfers and taxes.
According to the CBO report, the top 1% of households in the U.S. saw their share of income before transfers and taxes double from 9% in 1979 to 18% in 2022. Simultaneously, the share of income going to the lowest quintile decreased from 5% to 4%, suggesting that the economic compression primarily affected the middle class. This trend reflects a broader global concern about rising income inequality, observed in varying degrees across developed and developing nations.
Economists have pointed to several factors contributing to this shift, including technological advancements, globalization, and changes in tax policies. The rise of automation, for instance, has displaced many middle-skill jobs, while increased global competition has put downward pressure on wages for some sectors. Similar trends have been observed in other advanced economies, such as those in Europe and East Asia, though the specific drivers and policy responses vary by country.
The hollowing out of the middle class has significant implications for social cohesion and political stability. Studies by organizations like the OECD have shown that greater income inequality can lead to reduced social mobility, increased crime rates, and decreased trust in government institutions. In many countries, this has fueled political polarization and populist movements, as citizens feel increasingly disenfranchised by the economic system.
While the CBO report focuses specifically on the United States, the findings resonate with broader global debates about the future of work, the role of government in addressing inequality, and the need for policies that promote inclusive growth. Governments around the world are experimenting with various approaches, including investments in education and job training, reforms to tax and social welfare systems, and regulations aimed at curbing corporate power and promoting fair competition. The long-term consequences of these trends and the effectiveness of different policy interventions remain subjects of ongoing research and debate.
