That there's not a significant dent in the continuing issue raises some questions.
Expatistan's crowd-sourced info finds SF housing to be the most expensive in the world, and cost of living in general nearly there:
I'm not saying it isn't allocated effectively, just that the numbers themselves do not tell the whole tale.
I'm curious how many people live in SF on 12-20k, but that's irrelevant. If someone has accommodation and is able to earn wages as a steady state, it is obvious that their costs will be less than a homeless person who needs mental health treatment, rehabilitation and maybe even education before they are employable.
The figure that employed people can survive on is well below the lower bound for what is needed to rehabilitate a homeless person.
