"yuppy" boomers? That's like "jumbo shrimp". "Yuppy" literally came from "young urban professionals".
Boomers are now in their sixties at the very youngest. Most are not much part of the economy and they will be surpassed by Gen X in terms of wealth by the end of the decade. "You can't take it with you."
In terms of numbers, millennials will be the largest generation by 2030. I can't find any research regarding "generational wealth", but all of that boomer-owned real estate will have to go somewhere.
I agree that "yuppies" were, and are, the worst of humanity. The obsession with wealth, and things was excoriated in the movie "Fight Club", which was distributed in 1999. I see that the term "dinks" - dual income, no kids - is coming back into use. Maybe it's time for another "Fight Club" to remind the millennials of the faults of their progenitors.
