Paul Ryan, chairman of the House Budget Committee, explains his U.S. budget proposal to bring down the deficit. Ryan's Republican budget proposal is a bold effort to make a break from a status quo which is leading to higher levels of U.S. debt as a percentage of GDP. It envisions changes to Medicare, Medicaid, and the tax code. It is built on the idea that sustainable finances will lead to a better economic future for America, compared to small changes to the staus quo envisioned in Democratic proposals and the 2012 budge proposal of the Obama administration. It is also bold in its effort to tackle Medicare with a "premium-support" system, and Medicaid by turning it into a block grant system. It also incorporates the Bowles -Simpson President's Deficit Commission's ideas for simplifying the tax code.
