I'm very well familiar with homelessness, probably much better than an average person on this forum. I do agree that a lot of people are victims of circumstances, as I mentioned in my previous comment, and you are right that they often tend to be invisible to the wider society. For this category, getting housing usually solves majority of issues and they can take it from there. The other categories, whether it's mental problems or addiction or anything else, require much wider and more complex approach.
