LB, if you are a home owner, and could afford another home of equal quality shall we say, but smaller, as in downsizing, and in an area that has your network of friends, family, then i would agree. But having been offered a number of properties some time back, which were so bad that no one would live there, and so far from any decent bus/rail links, considered the options, and that was to stay put. People in council housing, not all perhaps, but many have invested money, time and effort in keeping these homes nice, and perhaps would have liked to have owned them, but just didn't earn enough, so had no choice but to stay put.
