The figure referenced in this tweet is likely referring to the 2021 net compensation chart we saw making the rounds a few weeks back. Indeed, it's correct, ~50% of all Americans made less than 35k per year in net total compensation in 2021.

In 2022, that figure rose to ~40k. So the trend is going in the right direction, at least. And IIRC, the chart does include teenagers, college students, people working part time or underemployed, etc.
