My sense is fewer Zoomers are interested in the grimy/underworld/rave vibe compared to Millennials and Gen X. It’s all the same to them.

My theory is that when Millennials were growing up there was still a strong ‘default culture’ that helped sustain a thriving counter-culture. One could move decisively between the two when bored/frazzled. Zoomers have grown up flailing around in a devolved soup of ideas. Everything’s edgy so nothing is.

I would just like to point out that members/former of every counterculture back to at least the 50s have said this about the younger generation; it’s almost a cliche.

I'd have to disagree this time. I'm in nearly early 20's and there's not really a prevailing and counter culture. Just two dozen different intercting culture. The lack of a overbearing monoculture does make it hard to effectively rebel.

So what is the counter culture these days?

I go to underground parties all the time and I actually don't see many people that seem younger than mid to late 20's.

Mostly late 20's early 30's millennials, and the crust punks of the 70's and 80's/
