Because the stigma of cage homes and subdivided flats is so much better? There's nothing to be ashamed about social housing especially when enjoying some ownership via democratic rights. If instead of ownership, people put their focus on livelihood issues, they'd be a lot more successful at creating successful community. As I said previously, the focus should be on improving incomes, not whether or not they live in public housing. Diversifying the job market, raising the minimum wage, regulating working hours, and compensating additional work is all part of that.
