The story behind the story is that "tax reform," as we know it, is dying. During the 1980s, no major piece of legislation better symbolized bipartisan consensus than the Tax Reform Act of 1986, which was regarded by both liberal and conservative experts as the best tax law since World War II. The basic idea was simple: Reduce tax rates and recover lost revenue by ending (or limiting) tax breaks. The struggle between President Obama and House Speaker John Boehner over the "fiscal cliff" indicates that this beneficial consensus has collapsed.
Traditional tax reform was about depoliticizing the tax code. We're moving in the opposite direction. --ts
