I experienced homelessness for a while in my 20's (back in the 90's, for reference). And yes, there were a group of people who were homeless and did not want to change. They would complain to everyone who could give them cash or assistance about how horrible their life was, and how they were victims of circumstance, but to other homeless people they were quite honest about their intentions to stay on the streets.

I never experienced people abusing me or stealing my stuff, but they were definitely difficult to be around. "ruiners" is a great name for them.

I moved on, getting some casual construction labouring work that allowed me to get the deposit for a rental property together (90's remember, not sure that would be possible today). And a friend let me housesit her place for a couple of weeks, which really helped.

I'm not saying we shouldn't help the homeless... I got a helping hand up from a construction contractor who didn't have to help me, and I'm grateful for it. But maybe don't be surprised if earnest attempts to help the situation aren't received well.
