Brian, the point I am making is that with such atrocious standards of repair by many councils, (and small-scale corruption in some cases), the stock of council housing would have declined and inevitable demolition would have taken place.
The RTB has improved the standard of countless "estates" beyond recognition and saved many from extinction.
Where I part company with past legislation is that many houses have ended up in the hands of private landlords and that is unsatisfactory. Many are good landlords but others are poor, just like some of the Councils in the 1980's only they charge more.
The tenants in the 1980's did not buy for profit, but hoped their families would benefit in due time. Hardly a wrong as you indicate. Just ordinary, decent, hardworking people trying to improve their lives.
