Another problem is the conflation of homelessness with heroine users. Forget the professional homeless (which my fiancee's parents have been at times). The problem is we treat both as "homeless" when they are very different animals. Social programs tend to elevate and help those who can be and it doesn't look like a dent is made because, statistically, the remaining homeless are either deranged (renting to newly rehabilitated homeless has wrecked properties I managed) or drug users.

>You can start by not judging the homeless.

It's not a complex topic, but the judgement is based on information and the existing information speaks volumes.
