@StillIRise1963 The supposed theory is simple - if you maltreat homeless people enough, they will magically figure out some way to not be homeless to avoid being tortured further.
Of course, almost no one becomes homeless by choice; and stress makes you stupid, not smart.
The real explanation is that in order to avoid thinking "There but for the grace of God go you and I," the architects of all this mess want to dehumanize their victims as much as possible.
