Conversation on homelessness

So i know that this really is not an article or a thing to help homelessness but was a very heated conversation i had with my friend today to dinner. I was talking to my friend about my classes and how i’m taking this course and i went into a lot of detail about it and what not and she was very intrigued by it. So talking more about the class we started talking about homeless people and her opinion on homelessness that it was all their fault and its their problem and how we should not help them and thats were i lost it. I told here that ya it might be their fault sometimes but a lot of the other times it is because its the way life runs its course and there are always natural disasters and after going in on this topic and conversation i sort of opened her eyes to a whole new way of thinking about it and talking about homeless people as another outcast but as equal human beings. I brought us how when i have spare change i always give it to homeless people to try and help them out in any little way i can, And my friend was so against that idea and i can in some ways see it as a bad thing she brought up to me how i can either feed into their addictions of some sort or i can actually really help them. She brought up the point of how when you give them money that you are just messing up our economical system and in someways i agree but i really do not understand how it is messing it up. Can some one please shed some light on this topic to help me better understand? I just wanted to sort of share another experience about how active conversations can change peoples opinions of others and also demonstrate a change in life.
