在2025年收官前，埃隆·马斯克主导的“政府效率部”(DOGE)以高调开局、低调收场：他在大选前约3个月与特朗普一次X访谈的随口提议，迅速演变为白宫核心项目，并在公开场合宣称要削减1万亿美元、随后改口至2万亿美元。

执行层面，他把企业式裁员逻辑搬进联邦体系：向超过200万名联邦雇员发送“Fork in the Road”邮件劝退，并强势接管机构，引发诉讼与司法阻止。Cato估计2025年有271,000名联邦雇员离职，多数为自愿；NPR称联邦系统常年流失率约6%–8%，但2025年升至约12.5%，迫使部分机构回聘。

财政结果与承诺背离：独立核查指出DOGE“节省数千亿美元”的说法夸大，DOGE自报累计削减最终“封顶”约2,140亿美元且仍被指高估；CBO数据显示联邦支出从2024财年的6.7万亿美元上升到2025财年的7万亿美元。马斯克在5月抨击特朗普税收与支出法案、并称其为“令人作呕的怪物”，此前他为共和党竞选投入约3亿美元；特朗普威胁终止补贴与合同后，特斯拉股价下跌14%。DOGE在11月被正式解散，较计划提前8个月；马斯克随后在11月19日白宫晚宴露面并表示政治是“血腥运动”。

Before the end of 2025, Elon Musk’s Department of Government Efficiency (DOGE) traced a steep arc: a remark in an X interview roughly three months before the election became a White House office, amplified by theatrical promises to cut $1 trillion and then $2 trillion from government.

Implementation relied on corporate-style disruption. Musk sent a “Fork in the Road” resignation email to more than 2 million federal workers, seized control of agencies, and triggered legal pushback that blocked or reversed many firings. A Cato Institute estimate puts 2025 departures at 271,000, mostly voluntary; NPR cites typical annual turnover of about 6%–8%, rising to roughly 12.5% this year, with some agencies later hiring back staff.

The numbers did not match the rhetoric. Fact-checkers flagged errors and exaggerations, and DOGE’s own savings tally topped out around $214 billion and was still described as overstated. CBO figures show total federal spending rose from $6.7 trillion in fiscal 2024 to $7.0 trillion in fiscal 2025. After Musk attacked Trump’s tax-and-spending bill in May and highlighted his $300 million campaign spending, Trump threatened to end subsidies and contracts; Tesla fell 14%. DOGE was officially disbanded in November, eight months early, and Musk later framed politics as a “blood sport,” while attending a Nov. 19 White House dinner.
