The "Big and Beautiful" Act, officially known as the "Massive Tax and Spending Bill", strongly promoted by the Trump administration in the United States, is an upgraded version of the 2017 tax reduction policy. Its core contents include a $4 trillion tax cut over the next decade, more than $1.5 trillion in cuts to social welfare programs such as Medicaid, and an increase in military spending and the debt ceiling by $5 trillion. The bill passed the Senate procedural vote on June 28 with a vote of 51 to 49, and is expected to complete the legislative process before July 4. Democrats criticize it as "robbing the poor to pay the rich," and there are also internal disagreements within the Republican Party regarding fiscal sustainability, leading to three senators voting against it. Tesla CEO Elon Musk has repeatedly attacked the bill for "destroying jobs and exacerbating the debt crisis," threatening to form another political party if it passes. Analysts point out that the bill could raise the U.S. debt-to-GDP ratio to 125%, intensifying social inequality and economic risks.
