This stuff is complicated so make sure you’re comparing like with like. Even the chart above ignored one critical adjustment: in 1970 just 5% of the population was foreign born, while today its 15%. Millennials are much more likely today to be recent economic migrants, or the children of them, than boomers. That drags the numbers down, but doesn’t imply anything negative about millennials’ economic status. Indeed, those immigrants are experiencing upward economic mobility, and are seeing themselves that way. The dour attitude among millennials seems to be mainly on the native born, who really are doing as well or better than their parents.

At least, they’re doing better economically. Thanks to social changes, they have less agency than their parents did. They have few opportunities to garner authority and respect in their communities. They’re not building families and getting the hope that comes from nurturing the next generation. They have many reasons to be dour. Their parents failed them!
