(AMERICAN PROSPECT) -- The United States has a revenue problem. Taxes at all levels of government are too low to balance budgets and, more important, to ensure America’s future prosperity and cope with an aging population. While many political and policy leaders argue that future revenues should reflect “historic norms,” this is a flawed assumption on which to base long-term fiscal planning.
Tax revenues have accounted for around 18 percent of GDP since World War II, and 18.3 percent over the past 30 years. The budget released by Paul Ryan and the House Budget Committee proposes average revenue levels at this same level—18.3 over the next decade. (Although an analysis by the Tax Policy Center found that the average would in fact be 15.4 percent.) The Simpson-Bowles plan, released in late 2010, proposed average revenues of 19.3 percent through 2020. Meanwhile, the Obama Administration’s 2013 budget proposal sets revenues at 19.2 percent of GDP over the next decade.
