The 'scary dad' is more mythological than you seem to present it.
Often, troublesome students have a really complex set of problems that can't really be dealt with by a single worn-out geography teacher, let alone a worn-out state school. It's not worth spending every lesson fighting with them, because that's a waste of resources and stops those that can learn from learning. These kids are clever too, because they know that they can only be told off- what's another telling off going to do?
Basically, they're outside the system. I was often told off for comparably small faults, but that's because I clearly could work within the system. If it helps, it's like a person that's had one drink against a person that's had about 20. At some point, you just say "well they're fucked, let's just make sure they throw up in the right place".
It's the same thing with customer service. The returns policy for most stores is pretty clear, but good retail practice is 'if the customer is really being a cunt, resolve it as soon as possible'. Again, it'd be insane to keep a disruptive customer in the store (driving out other customers) all for the sake of £2.50. Young retail staff have such strong egos that they'll refuse to refund the smallest purchase simply on principle.
>People who were bullied have demonstrably worse outcomes in later life, regardless of intelligence
Anecdotal but, I've found no real correlation. A lot of the bullies ended up messed up on drugs, teacher's pets ran out of people to brown nose.
