The issue is that in a place like London inequality rapidly leads to poverty because the income/wealth differentials are so high. On the ground, at the moment, housing is monopolised by those with decent careers or established wealth. From scratch? Someone a few years into a career in a well paid field may be able to afford a flat or house quite far out. A bog standard middle class worker may be able to afford to rent a small flat. Someone working in the supermarket full time will be sharing a flat or house; someone worse than that (e.g. children of the above, part-time or unemployed) will likely be more than one to a room unless they managed to acquire social housing when it was still available. Overcrowded housing leads to high stress levels, arguments, kids spending their time on the street, all sorts of nonsense.
