A number of homeless are indeed are victims of our terrible socio-economic system. However I have heard many homeless outreach workers say the same thing "The ones who stay homeless are the ones who stay addicted". Addiction is a serious issue and the challenge of beating it is nothing we should dismiss, however it is clear some people end up homeless due to drugs and stay homeless due to a refusal to get clean. When your life is centered around just getting high, you won't care much about anything else. All the horrors of living on the street disappear once you get your fix, and some people are okay living like that.

I guess I'm writing all this to say that homelessness is a very complex and nuanced issue. They aren't all victims, they aren't all criminals, they aren't all mentally ill, they aren't all addicts, and for some its the only life they've ever known.

This is why the conversation around homelessness is so difficult. People just latch onto their idea of what being homeless is then build their argument from there, dismissing the remaining context of the concept.

I highly suggest doing homeless outreach to broaden your perspective on the matter (look up a local Food Not Bombs group if you live in a city!). If that isn't something you'd like to do, there are plenty of videos on youtube that give you more insight into the homelessness experience. Obviously watch out for the videos that treat living on the streets as a spectacle or oddity, I absolutely hate these videos because they serve to shock and entertain, not educate.
