Another well-regarded source is the congressional budget office. The data linked below from 2014 is even more optimistic than my previous data because it uses household income instead of individual income. (because the distribution of individual incomes is skewed and growing even more skewed, median household incomes grow faster than individual incomes). The CBO data shows 26.1% growth in the incomes of middle quintile households since 1979. This growth is larger if you look at the lowest quintile, include taxes and transfers, or do both. The data goes up to 2014 and would show larger growth still if it went all the way to 2019. https://www.cbo.gov/publication/53597 https://www.cbo.gov/publication/53597
