It is a start.
Bad parenting is not limited to the lower classes, but it is significantly more prevalent in the lower classes.
Many parents' pop out kids willy nilly with all and sundry as a means to obtain more of my money from the state, and ultimately couldn't really give a toss about the kids - just so long as they are receiving my money in the form of benefits, they are happy to sit on their every increasing backsides all day drinking their Special Brew, smoking their fags and turning a blind eye to what their kids are doing.
It is no wonder so many kids are horrible little s0ds when the only example they have is their useless parent(s).
Now personally, I feel everybody should be means tested before they are allowed to breed, should have an intelligence test and all chavs should be sterilised.
