I can see your point...until I take account of the importance of continuity of schooling, how tricky it can be to arrange care services in a new place, and how important formal and informal support networks are to those in such circumstances. Even so, some people MAY move if they could get the more appropriate housing all their ducks in a row - the barriers are many though, it's not a joined up system. Should you have to move to Carlisle, when you've (perhaps) grown up in London, worked there, paid taxes there and have friends/family/other networks there, just because you have fallen ill or otherwise on hard times? (As far as I understand it authorities are obliged to house those with a connection to an area (plus refugees and the like), not just everyone/anyone. It's complicated, and I don't necessarily disagree with all the cuts in this area, but I do think that as usual some of the most vulnerable have just become even moreso.
