Aux-Etats-Unis, les riches ne paient pas moins d'impôts qu'avant. Bien au contraire :

(...) it is true that the top earners have increased their share of total income. Yet, as the nearby table shows, the rich showed more rapid gains in reported income shares in the 1990s than in the first half of this decade. The share of the richest 1% jumped to 20.8% of total income in 2000, from 14% in 1990, but increased only slightly to 21.2% in 2005. (...) By this measure, the Clinton years were far worse for "inequality." Notably, however, the share of taxes paid by the top 1% has kept climbing this decade -- to 39.4% in 2005, from 37.4% in 2000. The share paid by the top 5% has increased even more rapidly. In other words, despite the tax reductions of 2001 and 2003, the rich saw their share of taxes paid rise at a faster rate than their share of income.
