Sorry keepitsimple0 if you think the housing crisis is only 5 years old your definetly looking at this through partisan glasses and whitewashing 13 years of labour government.
It may have become a recent focal point, but even krugman was highlighting the effects of easy credit and the reliance on hpi during blairs later years, there where many,many articles around suggesting we need to address the problem, it's just that it was conveniently ignored by the majority of the electorate and government alike.
The difference between tory and labour house building policy during the election was that one side promised to build around ~20,000 more homes a year(iirc it was the tories - 200,000/180,000) which is still woefully inadequate to meet demand, especially considering most new builds are punted to overseas investors first, which also contradicts the recent mindset that this has only just started happening in the last 5 years.
They are both as shite on this situation as the other as there are to many VI's involved, haven't the Tories restricted the rights of nimbys to allow mass building?
This whitewashing of the previous government to the housing crisis is disingenuous at best.
