High-income taxpayers benefitted most from these tax cuts, with the top 1 percent of households receiving an average tax cut of over $570,000 between 2004-2012 (increasing their after-tax income by more than 5 percent each year). Despite promises from proponents of the tax cuts, evidence suggests that they did not improve economic growth or pay for themselves, but instead ballooned deficits and debt and contributed to a rise in income inequality.

Edit to add the chart - while technically the lowest fifth of earners saw a 1% cut in their taxes, the highest 1% saw a 6.7% cut.
