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 shrinking middle class and a growing concentration of wealth at the top. The data showed the share of national income held by the top 1% of households doubled, rising from 9% in 1979 to 18% in 2022, before accounting for taxes and government transfers.
The CBO report indicated that as the top 1% increased their share of market income, the lowest quintile saw its share decrease from 5% to 4%. This compression primarily affected the middle class, with the middle three income quintiles experiencing a decline in their relative economic standing, even after considering the effects of social safety nets and tax policies.
This trend in the United States mirrors a broader global pattern of increasing income inequality observed in many developed and developing nations over the past few decades. Factors contributing to this phenomenon include technological advancements, globalization, and changes in labor market dynamics, according to economists at the World Bank. These forces have often led to increased demand for highly skilled workers and a decline in the relative wages of those in middle-skill occupations.
The hollowing out of the middle class has potential implications for social cohesion and political stability, both in the U.S. and internationally. Studies by organizations such as the Organization for Economic Cooperation and Development (OECD) suggest that greater income inequality can lead to reduced social mobility and increased social unrest.
While the CBO report focused specifically on the United States, similar trends have been documented in countries like the United Kingdom, Canada, and Germany. Governments in these nations have implemented various policies aimed at addressing income inequality, including progressive taxation, investments in education and job training, and expansions of social safety nets. The effectiveness of these policies varies depending on the specific context and implementation. The CBO did not offer specific policy recommendations in its report, but the data provides a basis for further analysis and debate on potential solutions.
