Here's a brief economic history of the last quarter-century in taxes and growth. In 1990, President George H. W. Bush raised taxes, and GDP growth increased over the next five years. In 1993, President Bill Clinton raised the top marginal tax rate, and GDP growth increased over the next five years. In 2001 and 2003, President Bush cut taxes, and we faced a disappointing expansion followed by a Great Recession. Does this story prove that raising taxes helps GDP? No. Does it prove that cutting taxes hurts GDP? No.
