Marginal tax rates were cut substantially during the 1980s, and although rates were increased in the early 1990s, the marginal rates applicable in the highest income brackets were still well below the top rates of the 1960s and 1970s. How did the lower rates of the 1980s and 1990s affect the share of taxes paid by high-income taxpayers? Were the lower rates of the 1980s and 1990s good or bad for the economy? Discuss.
