As I see … homeless people are Marginals to the society. And by marginal they don't belong inside the society… In a way that No one ask for their opinion, no one is interested about how they passed the day, about what they have to say, no one gets happy when they arrive. they are even invisible. (Unless they do something like the 'visible people' do… as showing up at some fancy shopping, for example).
I reflected a lot about the marginalization situation and some times the different types mix up, and piles together.
Eg.: People who are in jail. They are marginalized as well. The thing is that many times even if they killed someone and made horrible stuff, they manage to get friends in jail, they learn a job, they get Into religion stuff, and when they live jail they manage to get their lives back and so on….
By the other hand, some people are marginalized Only because they have a mental disease (even without having committed any crime) they also are marginalized. Again: No one ask for their opinion, no one is interested about what they have to say, no one gets happy when they arrive… they are burden….
Then, if we mix mental disease together with not being able to pay their own bills, etc…We will have these folks ending up at streets…. And as consequence many times they end up getting into jail(…). (Some folks even want to get arrested in order to get out of streets)…
And there will be other people who ended up on streets and will manage a way to recover its financial situation and get recovered.
In all cases people need help (one friend, one institution, one 'God', one religion, one "hand"… in order to recover from this marginalization process … If that doesn't occur(…) You are going to end up being swept away from Earth having or not a roof over your head.
