#特朗普税改

In 2017, the Trump administration introduced the Tax Cuts and Jobs Act, which included key provisions such as reducing the corporate income tax rate from 35% to 21%, simplifying individual income tax rates, and increasing the standard deduction, while also limiting state and local tax deductions. In the short term, this stimulated a return of corporate investment and a rise in the stock market, with GDP growth reaching 2.9% in 2018. However, in the long term, it exacerbated the fiscal deficit, with an expected increase in debt of $1.9 trillion over ten years, and over 60% of the tax cut benefits flowed to high-income groups. The middle class saw an increase in their effective tax burden due to the limitation on state and local tax deductions, while companies engaged in large-scale stock buybacks rather than expanding production. Although the policy boosted economic confidence, it sowed the seeds of inequality and sustainability concerns, with some provisions set to expire in 2025 potentially triggering a new round of contention.
