How do we a) allocate s.h. and b) ensure that s.h. estates don't just become dumping grounds for the anti-social underclass (Marx's 'lumpenproletariat).
For A) We need to build more, including homes suitable for older people, the disabled, and include homes for childfree people. Also end RTB.
People register on waiting lists and wait their turn but get moved up if in dire circumstances (like homeless, DV, disabled and needing accessible home). The 'queue jumping' issue might cause resentment but that's solved if there was more SH built, because then there wouldn't be such long waits for everyone else who needs it.
For B) By not telling people to immediately move out as soon as they're not in abject poverty. Have more social housing available, so it's more mixed. A proper community. Working people on low but also medium salaries, the disabled, the elderly, families, child free couples, and single people.
My ideal model would be like Singapore, where about 80% of housing is public housing. I realise though that's probably too idealistic for the UK, but we could at least aim for more like things were 50 years ago. Back then it wasn't only people unable to work on benefits or the very lowest wages. It was people on medium wages too.
I get why people will think those like Bob Crowe, on higher than average incomes, shouldn't have it, but I think the majority in his position would choose to buy so it's a mostly irrelevant issue. He was the exception rather than the rule.
He recognised the value of stable community. People moving away for work or housing is one reason why there's increased social problems.
Lack of care and support, loneliness and isolation and feeling displaced (no coincidence the rise in people off sick with depression and anxiety).
Even when someone isn't disabled or older and doesn't need care, most people need a bit of temporary help or support at times. Not always financial. Practical or emotional. When they're a longterm member of a community, and know their neighbours and have family and friends nearby it makes a difference. Add in good public services and opportunities (work, education, training) and health is better so there's less state dependancy.
