减税刺激难掩赤字隐忧，美国“大而美”法案经济效应几何

Core Points - The "Big and Beautiful" tax and spending bill signed by President Trump on July 4 marks a significant legislative move, reflecting Republican priorities and diminishing Democratic political capital [1][2] - The bill extends many provisions of the 2017 Tax Cuts and Jobs Act, increasing tax exemptions and military spending while cutting social welfare programs [1][3] - Critics argue that the bill disproportionately benefits high-income earners and exacerbates income inequality, with potential negative impacts on low-income households [2][6] Tax and Spending Provisions - The bill raises tax exemption thresholds, including a $25,000 exemption for tip income and a $12,500 exemption for overtime income, while also increasing military spending by $157 billion [1][3] - It eliminates subsidies for clean energy and imposes stricter work requirements for Medicaid, affecting over 7 million people by 2034 [3][4] - Food stamp benefits will be reduced for approximately 40 million people, impacting vulnerable populations including children and the elderly [3][4] Economic Implications - The effectiveness of the tax cuts in stimulating economic growth is questioned, with historical data suggesting limited impact on growth and increasing federal debt [7][8] - The new tariffs are expected to have a negative effect on the economy, with rising consumer costs and potential inflationary pressures [8][9] - Employment levels may not improve significantly, as the bill's measures to increase work requirements could overlook the contributions of undocumented workers [9] Political Context - The passage of the bill reflects a partisan divide, with Republicans leveraging their slim majority to push through legislation that may disadvantage Democrats ahead of the midterm elections [2][6][10] - The upcoming midterm elections will serve as a referendum on the bill, influencing the political landscape for both parties [10]
