Elon Musk recently expressed strong dissatisfaction with the large-scale tax and spending bill passed by the U.S. Congress, arguing that the bill not only fails to achieve its fiscal reform goals but also exacerbates the budget deficit, contradicting the direction of his work at the Department of Government Efficiency. The bill was promoted by the Trump administration and includes key provisions such as extending the 2017 tax cuts, adding certain tax exemptions, increasing defense spending, and funding for immigration control, while also eliminating green energy incentives from the Biden era and raising the thresholds for low-income groups to access medical and food assistance.

Musk pointed out that the bill will increase the federal deficit by $3.8 trillion from its passage until 2034, directly impacting his previous commitment to cut $1 trillion in federal spending. Although his team has saved about $160 billion through layoffs and organizational adjustments, the results are far below expectations. He criticized the bill for "undermining the reform process of the Department of Government Efficiency" and emphasized that fiscal policy should balance scale and efficiency, rather than blindly increasing spending.

Additionally, Musk's relationship with Trump has grown tense due to policy differences. Although he previously invested heavily to support Trump's campaign and was set to lead the Department of Government Efficiency in 2025, their contradictions over the path of fiscal reform have gradually become public. On May 30, Musk officially stepped down from his government position; Trump confirmed his departure on social media, but the two did not communicate directly about the matter. Musk's departure marks a setback in his political endeavors and reflects the limitations of business elites' involvement in the traditional political system.
