According to the latest analysis by the U.S. Congressional Budget Office (CBO), the tax proposal put forward by House Republicans may further expand income inequality. Data shows that if this tax proposal is implemented, the top 10% of earners in the U.S. would see a 2.3% rise in income, while the bottom 10% might face a 3.9% decline in income. This policy assessment has sparked a new round of discussions on the fairness of socioeconomic distribution in the U.S. Analysts point out that this direction of tax adjustment may exacerbate the problem of wealth disparity in American society, and lawmakers need to consider a more comprehensive balance of interests for different income groups during the legislative process.
