I forget the name of the senator or governor who came up with what I think was a brilliant idea; a 4-tiered huge campus-style facility that included a hospital and treatment center, a fully staffed mental health clinic, a job skills training center and employment agency, and hundreds of small apartments.
I don't remember what state the idea person is in, either, or if s/he's still in office. This type of facility would cost trillions to build and staff, but imo it would be worth it. The plan was that all services would be free. Social workers would help the "residents" get whatever financial benefits they're eligible for; social security, unemployment, welfare, whatever; but no one is turned away for not being eligible. Residents enter the first tier: evaluate their needs and help them set realistic goals and objectives, enter the next tier based on those needs, start treatment and/or training, and so on.
At the end, (ideally) they come out clean, mentally reasonably sound, trained for a job and some job interviews lined up, and housed until they can afford their own place. It could take years for some residents but the idea included them working at the campus meanwhile, in housekeeping, grounds-keeping, janitorial services, meal prep, etc.
I like this idea. I don't know what happened to it.
