President Joe Biden released his annual budget Thursday, outlining his policy priorities for the year ahead. Biden's FY 2024 budget proposes to increase taxes for corporations and individuals with incomes above $400,000 as part of a plan intended to reduce federal budget deficits. Specifically, the budget proposes to increase the US corporate income tax rate from 21% to 28%, and to raise the tax rate on the foreign earnings of US multinational corporations from 10.5% to 21% while adopting an undertaxed profits rule.

For individuals, the budget proposes measures including increasing the top individual ordinary income tax rate from 37% to 39.6%, taxing capital gains income for high earners at ordinary rates, and imposing a 25% "minimum income tax on the wealthiest taxpayers." The budget also calls for higher Medicare health insurance taxes for individuals with incomes above $400,000 as part of a plan that seeks to avert the projected insolvency by 2028 of the Medicare hospital insurance trust fund.

President Biden's proposal seeks to increase revenue and reduce spending in order to put the federal government on a more sustainable fiscal path. However, given Republican control of the House of Representatives, it is unlikely that these proposals will be enacted without bipartisan support.

Question:  why not reduce wasteful government spending instead of increasing taxes?
