Yes, a good insight into a portion of society, but... I don't buy the bit about 'their poor mothers' losing control of their children, as if only males can contribute to producing decent citizens. That's chauvinistically patronising. I'm sure that fatherless families do suffer from good male role models, but in many, many cases, the fathers weren't. They were feckless bullies, drunks, drifters or drug dealers who just decamped when child-raising responsibility, which will be the buzz word now, proved beyond their limited abilities.
I know quite a lot of women whose rubbish husbands/sires of their children buggered off and left them to fend for themselves, but their kids were certainly brought up with a strong sense of right and wrong. In fact, one was my neighbour (sadly, now dead at 54 from recurring cancer), who'd had a violent husband who'd even broken the arm of their only son when he was barely two. She always made sure her lad came home for proper cooked meals (no foraging for micro-chips there), kept decent hours, and woe betide any of his mates who tried to keep him out late! The area in which we lived is deeply unfashionable (on the fringes of the notorious Whitehawk Estate in east Brighton), but I never met anything but the best respect from with the kids - we had a good time, plenty of laughs, and while some did suffer from rough-as-shit parents, they also saw through many of their own mums and dads' difficulties, and were very protective of them.
I never met one of them who I could imagine not helping someone - even just carrying in shopping - provided they were treated and talked with in the right way. You act snotty with them, they're going to be awkward, but give them some time, help them or their Mums out occasionally - you have some damn good kids at heart. In fact, they were all looking forward to taking up local jobs, even if ambition wasn't high on the list - just good, solid work learning to be mechanics, or working in music shops, etc. They all recognised their families (most of which worked) needed everyone to pull their weight, and while academically they were not very interested, they certainly did expect to be helping out from the age of around 15.
