Rep. Paul Ryan unveiled his budget plan and roadmap for the next 10 years. The proposal cuts $5.8 trillion from anticipated spending levels over the next decade. Highlights: Starting in 2022 Medicare would revert to private insurance plans. Elderly people would choose a private insurance plan from a list provided by the government and vouchers would be issued to individuals to help them pay for health insurance coverage. There would be a $15,000 cap on voucher subsidies. Medicaid, the federal-state health care plan for the poor would turn into a block grant to the states and be cut by $750 billion over the next 10 years. Domestic programs would be reduced below 2008 levels for the next five years. Defense would be cut by $78 billion — $100 billion less than the cuts recommended by Defense Secretary Robert Gates. The top tax rate for both individuals and corporations would be reduced to 25 percent from 35 percent, reducing the number of income tax brackets and eliminating loopholes.
