The core of Trump's tax reform is to stimulate economic growth by significantly reducing corporate and individual taxes. The corporate tax rate was reduced from 35% to 15%, the tax rate on repatriated overseas profits was lowered to 10%, and personal income tax was simplified into three brackets (10%, 25%, 35%), with the standard deduction raised to $24,000. Supporters believe that tax cuts can broaden the tax base and attract capital back, but opponents point out the lack of fiscal balance measures, which may drive government debt up to 111% of GDP. The tax reform also limits actual tax cuts for the middle class by eliminating multiple deductions and exemptions, while higher-income groups benefit more significantly, potentially exacerbating the wealth gap. In terms of spillover effects, low tax rates may weaken the cost advantage of manufacturing in other countries, triggering a global competition for capital. The current controversy revolves around whether economic growth can offset the fiscal deficit, and the prospects for congressional approval remain uncertain.
