Real wages have gone significantly since 2020 when COVID hit per the below link. This inequality index website includes both labor and capital - meaning not just wages but income from stocks. Yes the stock market has gone down, the rich own more stocks, and so rich made less money. Wages, the payment for only labor has been declining in real terms due to inflation outpacing wage growth. See this link and the sharp decline.https://fred.stlouisfed.org/series/LES1252881600Q

My link shows that real factor income for all but the top 10% of earners is up which includes wages and capital income.
Your FRED link will have to contend with the fact that those most likely to be unemployed at the start of the pandemic are lower earners which is going to shift up the wages for 2020.
The website you linked as I said includes capital and pretax income which is an absurd way to measure “income.” That includes stocks, 401K, houses, etc. if someone owned a house, the value went up, but if someone didn’t own a house their actual wages are still worth only about the same as 3 years ago.
