Ryan’s budget, his last before his term ends as head of the Budget Committee, would slash about $5 trillion in federal spending over 10 years, repeal the Affordable Care Act and reduce spending on domestic programs — including nutrition and education — to their lowest levels in relation to GDP in more than 60 years. The document promises to balance the federal budget by 2023 (with help from revenue gleaned from provisions in the Affordable Care Act it seeks to undo, curiously) and lower tax rates, even for the wealthy.
