You need to understand that for the most part, homeless are right where they want to be. They don't want that responsibility and choose to live like they do. There are far better places than a scummy city to be homeless in, but that is the easiest place to get booze and food while remaining without earning anything or being responsible for anything. And it's a mental illness as well as the addictions most have. And oh boy, don't try to home them, the house will be utterly destroyed. And if those houses are abandoned, good chance they already sleep there anyway, you just don't know it.
