I've not seen anyone denying that the affordability of housing is a massive problem in many areas of the country though? Apologies if I've missed that.
In my idealistic world I'd like to see the following
Many of our successful industries/companies relocating to areas of the country where there is great social need. The north/south divide is as profound as ever.
someone to sort out the disgracesful tax loophole that leads to wealthy foreign investors buying up acres of property in London and sometimes not even bothering to let it out, just relying on rising house prices to make their profit
reform of Landlord & Tenant Act
rent caps
banning of second home ownership
banning sale of council houses
banning of tenancies for life in council property
banning sale of housing association property to HA tenants
help for elderly people who want it to move from large family houses to purpose built mixed communities
compulsory purchase of long term empty properties and grants to people willing but unable to afford to fix them up, or subsidised "full repairing" rent applying there
that's just for starters.
I guess the massive increase in the divorce rate also has an effect on the need for new homes when compared to say 30 or 40 years ago.
