>The unfortunate reality is that mentally ill people that don't know how to take care of themselves are expensive. Think cleaning feces off of every imaginable surface, thousand room bed bug outbreaks, all the awful diseases that occur in unkempt showers or locker rooms. How will we keep so many people in confined quarters happy and busy enough to not cause massive problems?

Removal of high-density housing isn't solving that problem, it's just forcing those people into more desperate circumstances.
