This prediction market addresses whether former President Donald Trump, if elected to a second term in 2024, would reduce economic inequality in the United States by the end of his potential term in 2028. The market specifically measures the outcome using the Gini Index, a standard economic metric for income distribution where 0 represents perfect equality and 1 represents perfect inequality. The market resolves to 'Yes' if inequality is greater in 2024 than in 2028, meaning a successful reduction occurred during the term. This topic sits at the intersection of presidential policy, economic theory, and social outcomes, generating significant interest from investors, policymakers, and the general public. The question is particularly salient given the historical trajectory of U.S. inequality, which has generally increased over recent decades, and the distinct economic philosophies of the two major political parties. Recent developments include the 2017 Tax Cuts and Jobs Act passed under Trump's first term, which analysts continue to debate for its distributional effects, and the post-pandemic economic landscape characterized by high inflation and a tight labor market. People are interested in this market because it offers a tangible, data-driven way to forecast the impact of a potential Trump administration's economic agenda on a fundamental social issue, with implications for investment, social stability, and political discourse.

Historical Context

The trend of rising income inequality in the United States has deep historical roots, stretching back to the late 1970s. Following a period of relatively stable income shares in the mid-20th century, the Gini coefficient for household income began a sustained climb. According to Census data, the Gini index rose from 0.397 in 1967 to 0.489 in 2022, indicating a significant increase in dispersion. Major policy shifts have punctuated this trend, including the Reagan-era tax cuts in the 1980s, which lowered top marginal rates, and the Clinton-era welfare reform and expansion of the Earned Income Tax Credit in the 1990s. The 2001 and 2003 Bush tax cuts further reduced rates on dividends, capital gains, and estates. The most recent major tax legislation before 2024 was the Tax Cuts and Jobs Act (TCJA) of 2017 under President Trump. Analyses by the Tax Policy Center and the Congressional Budget Office concluded the TCJA provided larger average tax cuts as a percentage of income to higher-income households, though it also temporarily expanded the Child Tax Credit. The historical precedent suggests that significant, legislated changes to the tax code are a primary mechanism through which presidential administrations have attempted, with varying success, to influence the distribution of after-tax income.
