I think this is an important issue and hope this thread remains with thoughtful, appropriate comments from contributors. My comment here will focus on mental health. Without wishing to reveal enough detail to be identified, one of my relatives is almost certainly deceased in California, having suffered from mental illness and being dismissed when this relative and her/his spouse sought mental health assistance. (Bob Wells knows some of the details.)
Using California as an example, I think this report https://calmatters.org/explainers/breakdown-californias-mental-health-system-explained/ by calmatters.org discusses some of the difficulties. The KQED article "Did the Emptying of Mental Hospitals Contribute to Homelessness?" https://www.kqed.org/news/11209729/...tal-hospitals-contribute-to-homelessness-here includes a timeline of deinstitutionalization.
