Selfishness and greed. Anyone that stands up stands alone, and the others are quick to lick a boot as they grovel for scraps. For some inconceivable reason too many consider this preferable to standing together and working to make things better.
North American here. Funny how it's very much less "which is it?" And more "Yeah. Basically."
We've been culturally domesticated to not cause trouble for our bosses / schools / etc. If the State steps in after you cause trouble for enterprise, it's usually to kick you back into your place.
We might not live in a State dictatorship, but that only matters so far, because that State enables many tiny, petty dictatorships that more directly affect your life and run amok unopposed.
Somehow people accept petty tyranny in everything from corporations to universities to shifts at the burger joint. They'll get all riled up that some politician they never met is bawking about foreign policy, but their tail is tucked firmly when their company tells them they can't get sick days and arriving a minute late is a fireable offense.
Many have bought the lies of rugged individualism and competition.
"An insult to one is...well, that really sucks for you but I told you to just stay quiet. I'm just working hard doing what I'm told."
Like someone said before me: Even the most rebellious in us think twice about making our move, because many people simply think "That's how it is." And don't believe it can get any better.
There's not a lot of examples of collective action winning in recent history, so a lot of people don't even know how to begin to push back in the first place, besides writing an angry tweet or two.
Meh. Only "too pussy" to stand up for ourselves because it's against a dictatorship that will not hesitate to beat the absolute shit out of us, arrest us, torture us, and/or shoot us. Some of us do stand up for ourselves, and only some of what happens to us makes it to your eyeballs. College students are getting maimed right now for demanding that their tuition money doesn't go to investments that support Israel committing a genocide against Palestinians, but most people think it's just whiney kids getting arrested for antisemitically camping in the quad.
Things would be different if the protests were armed, which is why they should be.
A professor at my university tried that, but the students quite quickly made a huge fuss, got the principals office involved, and the universities lawyers informed said professor that what she was doing was illegal, and that she should stop before she got any more trouble. She stopped.
Possibly a poor translation from my side: I'm referring to the "head office" of the university, i.e. the group of people under the direct leadership of the principal, who have the highest administrative authority at the university.
