It really was the worst time in my life personally and I often felt like I just wanted to end my life.
Luckily I came through, and life as an adult is a lot easier. We still get grouped together with strangers at work, but there are unspoken rules how to behave as an adult that most adults actually follow. Also most adults have some degree of not wanting others to feel bad.
There are exceptions however. Some people are just mean.
I'm able to forgive a frustration. You cut me off, you have a bad day/parent in hospital - I'm able to live with that. That is in stoicism, radical acceptance etc. You do it just because - it's a different animal. "Just because" meaning, you take the power.
I'm finding it hard to discuss social hierarchies. They clearly exist. I suspect they have a much greater influence on many things, depression for example (seems to me like a "self own", making oneself lower in the hierarchy, maybe as a survival strategy, but coming with unintended consequences).
But people are unwilling to talk about it or get political very fast, because it seems to all hint to https://en.wikipedia.org/wiki/Might_Is_Right.
Structures and processes that place a high value on all people and their many quirks instead of conformity to an arbitrary leader are likely to do better in most situations than ones that don’t.
Which probably means being at the top of the social hierarchy in such a population is even more valuable.
So if your commentary meant valuable as in dedicated to the point that the individuals at the top become shit sponges for everyone else and do die as saints or martyrs, then yes, it is very valuable.
That being said, it depends on where you put value in life.
Selfishness is a luxury humans indulge in because those pressures are quite weak in modern days.
These two things are not mutually exclusive though. If you want to take your frustrations out on somebody else, you do it on people you can take them out on, not people you can’t.
And yeah, most of those little shits have issues. Just because someone is an asshole doesn’t mean they don’t have anxieties and insecurities that motivate their behavior.
