Look at how many things are being spoiled by the few: Visits to cinemas and theatres, trees destroyed, wildlife killed, arson, antisocial behaviour, graffiti, bullying, windows smashed, loud noise tormenting neighbours etc. They come in all shapes, sizes, ages, socioeconomic groups and include both sexes.
They live amongst us and make society a miserable place to live in. Money gives you the opportunity to avoid them, this includes private education of course where their behaviour is possibly kept under control by parents.
We've smugly jettisoned the usual social controls which kept a lot of this behaviour under control: Parental discipline, rules which were enforced, youth offending placements, proper sentencing, religion, community shaming and pressure, prison etc.
So we get what we wished for. A liberal, free, kind (hah), tolerant (hah) society where bullying and nastiness rules, everyone is miserable/mentally ill/distressed and the more destruction the better. I hope it's been worth it.
