My 4 Qs for Hilary ben after the death of the third way

My 4 Qs for Hilary ben after the death of the third way - my gf went to see him today in leeds..

1. Why did we need to do PFI on top of the greatest increase in public spending in modern history?
2. The greatest unequaltiyy is now house prices - could labour have considered methods of deincentivising the investment market of people’s houses?
3. By raising public sector & NHS workers did we fuel the pension crisis too?
4. Given the UK is still a hugely rich country, do you see the country returning to 45% public spending after the deficit is filled?

Answer pending, thoughts welcomed..
