A chart showing the disparity in income distribution in the United States. Wealth inequality and income inequality have been central concerns among OWS protesters.

Income inequality has increased over the last three decades with economic stagnation and unequal distribution of the wealth undermining some goals of working people. It is a focal point of the Occupy Wall Street protests. During the 1990s, economists began to release studies which showed the increasing income inequality in the United States, but was little-discussed until the cause was championed up by the OWS movement. OWS protests were particularly concerned with income inequality in America, in addition to corporate greed and the corrosive power of major banks and multinational corporations.

The phrase « The 99% » is a political slogan used by protesters of the Occupy movement. It was originally launched as a Tumblr blog page in late August 2011. It refers to the concentration of wealth among the top 1% of income earners compared to the other 99 percent; the top 1 percent of income earners nearly tripled after-tax income over the last thirty years according to a Congressional Budget Office (CBO) report.

The report was released just as concerns of the Occupy Wall Street movement were beginning to enter the national political debate. According to the CBO, between 1979 and 2007 the incomes of the top 1% of Americans grew by an average of 275%. During the same time period, the 60% of Americans in the middle of the income scale saw their income rise by 40%. Since 1979 the average pre-tax income for the bottom 90% of households has decreased by $900, while that of the top 1% increased by over $700,000, as federal taxation became less progressive. From 1992 to 2007 the top 400 income earners in the U.S. saw their income increase 392% and their average tax rate reduced by 37%. In 2009, the average income of the top 1% was $960,000 with a minimum income of $343,927. In 2007 the richest 1% of the American population owned 34.6% of the country’s total wealth, and the next 19% owned 50.5%. Thus, the top 20% of Americans owned 85% of the country’s wealth and the bottom 80% of the population owned 15% —an example of the Pareto principle. Financial inequality (total net worth minus the value of one’s home) was greater than inequality in total wealth, with the top 1% of the population owning 42.7%, the next 19% of Americans owning 50.3%, and the bottom 80% owning 7%. However, after the Great Recession which started in 2007, the share of total wealth owned by the top 1% of the population grew from 34.6% to 37.1%, and that owned by the top 20% of Americans grew from 85% to 87.7%. The Great Recession also caused a drop of 36.1% in median household wealth but a drop of only 11.1% for the top 1%, further widening the gap between the 1% and the 99%. During the economic expansion between 2002 and 2007, the income of the top 1% grew 10 times faster than the income of the bottom 90%. In this period 66% of total income gains went to the 1%, who in 2007 had a larger share of total income than at any time since 1928. This is in stark contrast with surveys of U.S. populations that indicate an « ideal » distribution that is much more equal, and a widespread ignorance of the true income inequality and wealth inequality.
