Article claims about a 75% success rate, though success isn't defined. But that means for a guy with 13 units, he's basically guaranteed at least one failure (98% chance).
If failure means his place gets trashed with minimal support from the original agency due to understaffing or budget problems, then we need to reevaluate the setup, because that's not a level of risk that seems fair.
I know people don't like to see their tax dollars going towards people's salary, but this sounds like a pretty good case for more social workers.
