Reading all that's been happening with young men attacking people in Dublin, it made me think of anyone I knew personally that ended up in criminality but came from a middle to upper class background.
There's only one lad I know from my secondary school in Stillorgan that fucked his life up. Was actually very intelligent and did reasonably well from 1st to 3rd year and even got the highest Junior Cert. He had autism though and couldn't cope with stress. 5th year was a disaster and heard he got into drugs, started assaulting parents, robbing them. That was seven years ago and last I heard, he's living illegally in the States and a small time drug dealer.
But I'm sure stories like these are far more common in disadvantaged areas.
