Under Donald Trump's tax plan, the top 1% would see their after-tax incomes increase substantially, gaining over $250,000 on average. In contrast, Bernie Sanders' tax plan is designed to fund universal healthcare, and would significantly decrease after-tax incomes for the top 1%, costing them on average nearly $160,000. The Trump plan favors the wealthy over middle and lower income groups, while the Sanders plan aims to redistribute resources from the highest earners to support social programs.
