Since 1979, the nation has seen a rapid and significant increase in income inequality between low- and middle-income Americans on the one hand, and the wealthiest one percent on the other. Over that time span, the bottom 99 percent of American households saw their incomes increase by an average of just 14 percent after inflation. Meanwhile, the wealthiest one percent saw their inflation-adjusted incomes balloon by 175 percent on average—or fully 12.5 times more than the income growth realized by everyone else.

This Report provides a detailed analysis of both Governor Bruce Rauner’s and the General Assembly’s two very different proposals for the FY2016 General Fund budget. Both budget proposals would cut services and increase the state’s deficit due to the phase down of the temporary tax increases in the state’s personal and corporate income tax rates that became effective on January 1, 2015. Collectively, those income tax rate cuts will cause Illinois’ General Fund to lose $4.6 billion in recurring revenue over the course of the full fiscal year.
