You've got no clue. I wandered feral because noone wanted 10 teenagers in the house.
We misbehaved at times because everything was a paid for service and there just wasn't the money so we found our own fun.
My parents weren't neglectful, they were working shift jobs to make ends meet. One had a violent upbringing, the other was moved around for years before joining the armed services for years but didn't have transferable skills.
My parents cared.but it takes generations to break poverty and the social issues thst come with it. My brother and I respectively earn 40k & 80k and out kids go to good schools, we socialise with the nice middle class folk who work nice middle class jobs and live on new estates where we all take our kids to hobbies in the evening, soft play at the weekend (something that would have been a once in a summer holiday treat as children) and ask questions about phonics. Shit my parents could never have done, nor were they brought up to do it.
The incident for that poor man is horrific, any yes, it may be a symptom of society, but that society was always there, modern standards have just been eroded, ironically, by modern standards.
So get off your high horse.
I was a poor kid, no money for clubs, what do you propose kids from those demographics do? Obviously not beat people and damage property, but what actual positive stuff I'd there for them, free, at evenings and weekends? And no, we didn't qualify for benefits (that i saw), like many people, my parents were hard working and scraping by.
