The Enormity of the Fiscal Gap

Greg Mankiw found an article that describes strikingly our financial position:

A study we conducted at the Tax Policy Center found that Washington would have to raise [income] taxes by almost 40 percent to reduce -- not eliminate, just reduce -- the deficit to 3 percent of our GDP, the 2015 goal the Obama administration set in its 2011 budget. That tax boost would mean the lowest income tax rate would jump from 10 to nearly 14 percent, and the top rate from 35 to 48 percent.

What if we raised taxes only on families with couples making more than $250,000 a year and on individuals making more than $200,000? The top two income tax rates would have to more than double, with the top rate hitting almost 77 percent, to get the deficit down to 3 percent of GDP.
