Seems like you'd just look at the median wage among groups of similarly-aged people to get a "final answer." Like this:

Its not a stretch at all to say that median incomes have been stagnant since the late 90s.

Am I missing something? In all of those graphs I see at least a 20% growth in income comparing 1989/1999 and 2019.

Sure: people's lives don't linearly interpolate; 2019 was the first year to be better than 1999 for several age brackets.
