Im conflicted. I was homeless (a traveler, 18+ countries) for the better part of 11 years, and was always looking for work (and I always found it) - so I think this is ok for folks needing money. However, its bad in the sense that it for all intensive purposes turns people into intimate objects.
Still torn on this, and as someone deeply involved in the technology community, as well as having been 'homeless' in many countries, albeit teaching workshops on linux, wifi technology (am currently working internal IT and have a house that I own)- I'd say that overall, this is neither a good or a bad thing. It is what it is.
One caveat: PLEASE, potential hiring agencies/recruiters- try to not hire obviously strung-out people. Its hard to determine, but, lets not fuel obvious abusers of hard drugs' addictions. Another hard one, because many home-owning, so-called "responsible members of society" abuse drugs and the houseless/homeless are scapegoated constantly for this, unfairly.
Hobo-hotspot here we come, this is our dystopian future.....
