This isn't about poverty.
This is about mindless thugs that think this is fun. Race, background and environment doesn't make this happen. Thuggism, herd mentality and idiots cause this. Don't even blame anything else or look for excuses.
I understand the allure, having spent a good few years smashing windows, torching cars and tagging during my early teens because there was bugger all else to do and a lack of parenting. Almost all of the lads I ran with back then are now in dead end lives on council estates, I got my crap together and got out.
Boredom and lack of responsibility are the key factors, and they are most prevalent in poor environments.
Edit: If it was me 20-25 years ago, i'd probably be part of the problem.
