The inflation-adjusted median income of U.S. households rebounded last year to roughly its 2019 level, overcoming the biggest price spike in four decades to restore most Americans’ purchasing power.
This was for 2023 and the job market was hot that year. If you switched jobs you probably got a double digit pay rise, and many people were doing it. That's what drove the number.
However, the job market is kinda crashing right now in 2024. So I don't think it's a trend that will continue.
