It can’t be proven, but common sense would say GenZ are the most nihilistic because they have to work the hardest to even get to the middle, let alone the end.

I’d say the people in the beginning and end have a tangible resentment, and not necessarily an existential crisis. In other words, GenZ would be resentful of having to start fresh against the barbarian Millenial/Boomer horde, and Boomers would be resentful of any attempt at reformation where their scraps from the race would be worth less.

It’s only Millenials who would neither resent GenZ or Boomers because they were already GenZ once upon a time, and know they have to become Boomers to survive.

That would be my best argument for why Millennials are in some deep psychological shit.
