10% a success depends on the alternative. If that 10% is an avoided AIDS case or Hep C or whatever, and a lifetime of expensive medical care, and those cases in effect pay for the others who fail, no problem with me.I would not consider a 10% success rate a success. As I suggested earlier, there are some types of homelessness I would support paying for their aid. There are other types I would not because I do not think that the odds favor them changing just because they have a free roof over their heads.
We just apply different standards to who should receive aid, which is understandable. I don't much care why they're homeless, only what works best and is better for them and society in the long run. Some here think the potential for abuse is high and maybe they're right. If so the programs long term might be a failure. All I have to go on are the studies to date, which are of mostly pilot programs, and certainly are only open to a small slice of the total homeless population. Perhaps these programs will work for only a small slice of that population. We know our little charity doesn't work for many because to stay they do have to follow some basic rules - look for work, cook, clean, stay sober, get treatment. Theft is permanent dismissal with no chance of return. Getting high gets you kicked out, but when sober can return. Etc. Those are our rules, but if different rules work better, OK.
