Question: has inequality increased or decreased in the us?
Answer: Income inequality has fluctuated considerably since measurements began around 1915, declining between peaks in the 1920s and 2007 (CBO data) or 2012 (Piketty, Saez, Zucman data). Inequality steadily increased from around 1979 to 2007, with a small reduction through 2016, followed by an increase from 2016–2018.
