Joe : .... "the same tenants who then sub-let and made huge profits."
There may be a group of council tenants who want to escape living on a crime ridden Council estate, and subletting their council flat is the only way they can rent elsewhere in the private rental sector. Just an escape for a better safer life.... Or perhaps, a pensioner has sublet their flat to live in Spain.
People can discuss the ethical or morals of doing this.
Certainly those those people who got a council house by fraud should loose them. But I wonder if this is as straighforward as it seems....
