Earlier quoted context omitted.
Wages have stagnated. Your graphs aren't really relevant to this question; so what if per capita disposable income has increased? That doesn't say anything at all about wages of people in America. Here is a more complete picture, with words and discussion and multiple graphs too: https://www.pewresearch.org/fact-tank/2018/08/07/for-most-us...
My graph also shows median income, and it clearly shows it has not stagnated, but risen, and not by any small amount.
There’s a story to tell here, but you’re not showing it.
