I wonder how many people here have visited a council estate recently? I know that the demographics have changed HUGELY since I was a kid. As a child my Mum was the only single mum in our court, the rest of the houses were occupied by families. But the reverse is now true. There is virtually no social housing left in the housing estates members of my own family remain in, that's not occupied by single mothers. I'm not quite sure why barring realistically low aspirations among the lower-working classes, but the fact is that very little social housing is under occupied. The tiny minority of tenants who are under-occupying homes, should not be punished for failing to breed - or having done so and had families move on. Cap private rents. Build more social housing. And incentivise young girls - including those with babies or small children - to get educated or trained in something fulfilling.
