Yeah, boomers in 1988 would have been about the same age as millennials are now, and this kind of nonsense was not still being regularly written about them back then. Nor was it for gen Xers in 2007 when they were the same age.
Boomers in 1988 were the only coherently identified generation outside of WW2 veterans. They were also called the "Me generation" too.
I'd also point to the "yuppie" phenomenon. Newspapers back then could not stop writing about yuppies coming to destroy property values and how suburbs would all die. It was actually pretty similar to the accusations that millennials kill various industries.
