1. I saw more or less the same behaviour as a teenager about 15 yrs ago. Sixties-style rebellion was entrenched, & people knew it was a product. I think things like punk and neo-romanticism were healthy youthful rebellion—now commoditised. Young fogeys are refusing to mature.
2. Also, it’s not “the Boomer’s” fault. Their parents passed the social legislation to make all this possible. Acting like a yuppie and wearing a suit is as much “Boomer” as being a hippie—same generation. The roots are much deeper than the Boomers.
