It's not even a "top few percent" thing. It's an exercise in creative measurement.

A large fraction of the boomers were useless hippies for many years in their 20s so they were living hand to mouth, no assets. Everyone since went to work. The boomers when they did get serious quickly could afford houses got mortgages, putting them in the red for years. Everyone since has had to wait way longer to be in the red like that. So of course when you pause and take a static measurement it looks like generations since are "doing ok" because at whatever point you measure there's more of them banking assets to get to the next step.
