The worst, or maybe the best, part of your post is that you don't realize the American youth from the 60s literally created this generation with their greed and entitlement.
The counter culture was a minority. Recognizing that is crucial to understanding the current climate.
It just so happens the creative output from those aligned with that culture has dominated more recent generations(Sesame street, Free Willy, Fern Gully, all that). In a sense "they won". But those not on-board are still around, and there is a lot of resentment.
I'm only 36 and while I was raised on this stuff but even so a LOT has changed and "progressed" from when I was a kid. Can you imagine how much has changed for those who lived through the civil rights movement?
Not OP but it's the grown up subset rather than the Abbie Hoffman set. Hilarious pranks are hilarious but sesame street is more widely and subtly influential.
I think they're pointing out that "the hippies" were a very small % of people their own age with an out-sized popular culture representation that doesn't reflect the sentiments of the rest of that generation.
