Exactly. Social housing is not the problem, its the people in them. Many are fine, I lived in a concrete council house til I was 21 and luckily ours was a nice area. I firmly believe that was down to the mix of people we had on the street though, very few dumped washing machines or cars! 2 streets away on the other hand, you think the bin men fear to tread.
The house is not the issue, the area is not the issue, its the people. A house is just a pile of bricks, the area a collection of these. Seems to me when you have crap neighbours then standards drop, and when you have good neighbours standards improve. The issue is that people who rent care less about their houses, so areas of high rental are usually the shitholes. Still all down to the people though, not the houses.
