Yes it was a sweeping statement.
The houses themselves are generally better built and better proportioned than the equivalent private(built for profit) houses. The best ones have all been bought now anyway.
As regards the tenants they vary from really nice and decent(as robo's mum) down to the dregs with a mixture in between. The same, to a lesser degree, can also be said about private houses too.
imho, it's the young unmarried girls with loads of kids, on the social etc, who are the worst. They don't pay for anything so don't care for anything either, they are a drain on the country, but that is a different subject.
(it is also another sweeping statement).
