Also things like: "U.S. economic growth is not translating into higher median family incomes. Real GDP per household has typically increased since the year 2000, while real median income per household was below 1999 levels until 2016, indicating a trend of greater income inequality"

And: "Total compensation's share of GDP has declined by 4.5 percentage points from 1970 to 2016. This implies that the share attributed to capital increased in that period."

Also: "Measured relative to GDP, total compensation and its component wages and salaries have been declining since 1970. This indicates a shift in income from labor (persons who derive income from hourly wages and salaries) to capital (persons who derive income via ownership of businesses, land and assets). This trend is common across the developed world, due in part to globalization.[16] Wages and salaries have fallen from approximately 51% GDP in 1970 to 43% GDP in 2013. Total compensation has fallen from approximately 58% GDP in 1970 to 53% GDP in 2013"

The whole picture here is a pretty mixed bag and not at all a case for how median wage to the average worker is phenomenal.
