the homeless

Okay so I came across this picture on FB (yes I know terrible place for news) but it just makes me wonder why this is the case is so many places.
And I know it's because you are required to have an address and a phone number so I got to thinking, why couldn't they just out the shelters? That way they could actually get a job? 
Do you guys think this is an option / would work? What should we do about the homeless who can't get a job?
