I know it's not the answer:

It's as if they aren't actually against the system in which they failed (are "unhappy" / suicidal), but see the people who they consider inferior actually doing better than them (not being suicidal), and just ragequit hitting the people who they always saw as stepping stones / ego reasurances.

The idea of the system being unfair obviously occurs to them, but their most fundamental anchor in life is that they are above other people, and yet that other people are happy, unlike them.

So, they believing first and foremost that society is "rightfully" shaped like a pyramid, causes it.

That is also the fundamental understanding of most "conservatives"

Shit it makes way more sense now that when I started writing it
