When housing costs are as exorbitant as they are, everyone is much closer to homelessness than they were before. If someone is laid off in the bay, they have significantly less time to find a new job before they cannot afford housing compared to more affordable areas.
Once you are actually homeless, mental problems and drug issues can become a self fulfilling prophecy, especially if you moved to the bay from out of state and have no local support network.
> Homelessness is - for the most part in San Francisco - a choice and/or a result of mental illness and drug addiction.
This is.. a very harsh take. Mental illness and drug abuse I can see, but a choice ? That is a serious claim that requires serious evidence.
