The EPI article Wage inequality continued to increase in 2020 by Lawrence Mishel and Jori Kandra (12/13/2021) provides the graph copied here. As for the share of the overall pot:
This disparity in wage growth reflects a sharp long-term rise in the share of total wages earned by those at the very top: the top 1.0% earned 13.8% of all wages in 2020, up from 7.3% in 1979. That marks the second highest share of earnings for the top 1.0% since the earliest year, 1937, when data became available (matching the tech bubble share of 13.8% in 2000 and below the share of 14.1% in 2007). The share of wages for the bottom 90% fell from 69.8% in 1979 to just 60.2% in 2020.
The article also has two tables of data that could be useful in stats or QL course.
