Christ, give the new government a chance will you!! They've not been in a couple of weeks yet and you seem to be blaming them for this. Perhaps you think they can solve the problems they have inherited from Labour in 5 minutes?
this problem started fairly and squarely with the tories although left to carry on by labour
the right to buy was started by thatcher the money from sales wasn't allowed to be used for building new homes causing an ever growing shortage off reasonable cost rental housing although labour tightened the criteria the haven't stopped the right to buy completely
it has served both parties as the money raised has been used to improve the housing stock with excess monies returned to the treasury by a reduction in the money from central government towards running cost off the same amount
