They're trying justify making the selfish choice in the prisoner's dilemma and abusing the trust that is so useful to cooperative/polite society.
They also get annoyed if coperative society is rational enough to slap them with the reciprocity they deserve after being found out for being a twat.
But I think they rationally they do want a 2-tier society, where lots of people in one tier cooperate to build trust and wealth (generally using trust instead of lawyers), then their tier extorts that wealth. And they find ways to protect themselves from consequences (generally using lawyers).
I'm sure many of the brainwashed masses don't know which tier they're in though.
I think the idea is that someome wants to avoid being "cancelled" after they've been exposed for for abusing social trust and norms of behaviour - usually to their own benefit.
So they denigrate or attack anyone exposing their shitty behaviour or anything similar. If they can do this they can contine to be cunts to society and avoid being ostracised by it.
But once they can get away with it, one can systematically exploit social trust and norms repeatedly, and presumably grow the power and influnce of their subculture. Even at the cost of overall the weath of the encompassing society - it won't matter to the dicks so long as they can extort a bigger share of the smaller pie.
Polite society will unfortunately struggle to effectively ostracise the people who do this because they're (rightly) worried about due process, accountability, fairness, and miscarriages of justice.
