David Wessel points to some problems with the Paul Ryan budget proposal. Ryan's plan does not balance the budget till after 2030, and Congress would have to raise the debt ceiling each year till then. The changes to Medicare Ryan proposes would limit how much the government spends, but the savings from this do not come for a decade, as people expected to retire in the next 10 years will still have Medicare. Ryan's proposal shows how deep the cuts will have to be if deficit reduction is done without raising taxes. Pete Domenici and Alice Rivlin who developed a deficit reduction plan, said they were disappointed that the Ryan plan "fails to address the need for new revenue," which they consider crucial for truly tackling deficit reduction. The Obama budget failed to offer a comprehensive deficit reduction plan, leading to openness for new ideas. The health care delivery system in the U.S. needs to be efficient and costs need to come down. Ryan's proposal gives no idea where the efficiencies will come from. Would they come from competition between private insurers? How will escalating healthcare costs be controlled. Another consideration is that even with its problems Medicare is less costly to administer than private insurance. Everything depends on seniors shopping vigorously for the best premiums because risks and costs are borne by seniors, with the idea that this will somehow control escalating medical costs....
