Choice based lettings, a change for good?

I was recently asked what do I think of CBL (choice based lettings). I have been in social housing for 24 years now, and my very personal opinion is it has contributed to problems no end. I remember as a manager knowing what was vacant and who was waiting . We matched people to communities that existed. But now, no matter who applies, if they are next in line they get it. Without convoluted local lettings policies it is pretty much ........next please. This takes away the continuation of stable communities. Young and old forced to live together. ASB ???? Yes a lot is clash of lifestyles rather than bad people. But what choice do we have? Do I agree in social engineering??? NO But in any other sector do you get told you are next have this??? No before I bought I had a chance to see my neighbours, and see if the area was for me. When I rented privately the same, but why in social housing are you told here you go be grateful??? Times have now changed, welfare reform has changed the paying field, again!! Some properties simply will not be let unless people want them through choice not gratitude . But maybe I am just getting old and cynical.
