The number of people I am acquainted with that have not been affected in some way by people using drugs can be counted on one hand.

I don't think the homeless situation and drug-abuser situation are so easily extricated from each other; nor do I think that there is one solution.

I wholeheartedly agree that something should be done about the garbage, the filth, the able-bodied that would rather be parasites than prideful; but the issue is that among the riffraff are people that genuinely need help. I think that until the causes are rooted out and addressed, this will continue to spiral out of control.
