Can't you see, their condition is a manifestation of your thinking. What if instead, we took the view that they ought to be guaranteed housing, schooling, healthcare and food. And all this at minor inconvenience to you, some money. Maybe you and your boss already have more than enough money and looking for a way to improve your quality of life and incidentally help someone else too?
I'm not suggesting anyone be murdered. I'm suggesting that if someone is given $5 and they haven't eaten in 3 days, and they choose to buy heroin or gin with it, they are going to die pretty soon. The alternative world where you stop that death, fix them up and send them right back out to destroy themselves just the same, with the same conclusion, but with a much longer timeline, isn't a better or more compassionate world, it's a morally lazy world where people make believe that they are doing something 'good' by delaying a death while doing nothing to improve that very life, and simply prolong a horrible life. In the meantime that miserable existence makes everyone else worse off, and the city unlivable.
I'm certainly not calling for anyone to be murdered or anyone's rights to be violated in any way, I am very much for not subsidizing the behavior by delivering sandwiches to people so they don't have to take a break from their drinking.
For your sake, just hope the robots don't feel the same as you when they takeover. "Oh, he'll never figure out the system, let's let him die."
Well, it does work, I mean it does provide protection from the weather. However, you can't trust random people with access to something without supervision, because many will completely destroy it. You can't provide personal supervision to each person so that they can have a private space, because that would cost an incredible amount of money. Finally you can offer some kind of barracks/homeless shelter environment where you have an open space that is easy to supervise to the level of preventing arson and other overt destructive acts. HOWEVER, this means bringing together a bunch of homeless people in one space, and you can't provide enough supervision to prevent them from victimizing each other. Read up on the topic, time and time again homeless people will say that the most dangerous thing about being homeless is you have no protection from the other homeless people.
So on a more personal level, do you really think that super, super obvious ideas haven't been thought of before, and the world just needs someone like you to swoop in and say 'give them shelter!'?
