May just be coincidence but this is the second time in the past few weeks I've heard about this, and I'm curious. Would you mind going into more detail?
There's a LOT to chew on in there.
Note that I don't disagree with your notion that abuse is abundant in all human societies.
If you assume that abuse can be caused or influenced by more than one thing -- which I believe makes sense but you might disagree -- then it doesn't matter what communism was doing if we're talking about capitalism.
The thing with banks is that they aren't productive in the first place. They're scalping off whatever they can get, with fierce competition. If you're fresh out of college and get hired into these places, you can't just walk away without risking your whole career. It's a monopsony. That's what enables abuse, human nature takes care of the rest.
This is fine. It's a hostile work environment. But if everyone's on the same page, it can, I don't want to say work, but not totally suck. Especially if there's good money.
Threatening to punch people, smashing things near someone to show them who's boss and "getting physical" is different. It's abuse. It's illegal. It was somewhat commonplace in and before the 80s [1], but it has not been common for decades now nor should it be.
[1] I have a theory for this, and it involves leaded gasoline.
