"For most U.S. workers, real wages have barely budged in decades"
The TL;DR is that in 1964 the average hourly wage was $20.27. As of 2018, average hourly wage was $22.65.
1974 median individual income was $28k 2024 median individual income was $45k
Over 50 years that’s a decent amount of growth. Obviously it could be better but it’s not nothing.

Sure but pretty sure with your 1974 28k you could buy a nice house, whereas with your 2024 (equivalent) 45k you can buy an OK car, not a house
In theory this graph is already inflation-adjusted.
In practice, I think this shows why economic statistics are borderline lies.
The problem is inflation. We have no way to reliably measure it over any long time-frame. Make the time long enough, and it even stops making sense as a concept.
