Stiglitz points out that our progressive tax system is far less than progressive in implementation, particularly at the very high end.

The richest 400 individual taxpayers, with an average income of more than $200 million, pay less than 20 percent of their income in taxes — far lower than mere millionaires, who pay about 25 percent of their income in taxes, and about the same as those earning a mere $200,000 to $500,000. And in 2009, 116 of the top 400 earners — almost a third — paid less than 15 percent of their income in taxes.
