Ideally, what I’d like to see is this… It would probably take 1.5 to 2 billion to pull off:
You build and staff a state of the art medical facility for mental health and addiction treatment, including the ability to hold people long term if necessary.
You build and staff a facility for job training and placement, including specialized support for people with criminal records. This would also need to include interview and resume skills. Assistance for email, phone, and Internet, but also clothing assistance, laundry assistance, and the like for interviews.
You build and staff a facility for housing support. Like work assistance, there needs to be specialized support for people with criminal records. But also a permanent address for mail.
Once all that infrastructure is in place, you sweep the streets.
People who need mental health and addiction treatment get institutionalized and treated until they are healthy, then they get released to the job and housing programs.
People who have no job get the job assistance program.
People who have a job get the housing assistance program.
People with warrants or otherwise engaging in crimimal behavior (stolen cars, stolen bikes, other material) get arrested.
People who are otherwise able bodied, but who are homeless by choice because “I ain’t part of your system, maaaan!” get their asses kicked and pressed into service cleaning up homeless camps.
