Seems you are already on board for at least part of the program. And what you are suggesting is perfectly reasonable, although I don't agree in every detail.Only one correction here....The proposed program is not an indefinite proposition....While I think 12 months is too long, I do agree that the study should be around 6 months, and include training, and housing for 6 months, with a caveat that if they are succeeding, then it can be extended monthly for up to the following 6 months....
It would include requirements for
Employment
Drug testing
Training in a marketable skill set
and therapy is required....
and I am going to throw in training in budgeting, and money management (in a rudimentary way) to curb unnecessary spending....
