That's the average. Please compare the median wealth (especially seeing the absurd paper wealth of crypto bro and stock influencers who are almost exclusively millennials).

[Edit] also inflation is calculated based on average consumption. So you will notice that toys, clothing and electronic devices (TVs, cooking robots), all cheaper and cheaper (due to enshitiffication and quality decrease) count more for inflation than education, cars, housing and probably a lot of other stuff a 25-35 yo care more about.
