This is correct. Everyone pretty much agrees that these areas are a symptom of a problem. Nobody agrees on what that problem even is. Further, various factions (there are more than two) seem to believe that the problem is exacerbated by what other factions believe to be a proto-mitigation. E.g. see discussion of rent control -- some people believe that rent control keeps people out of public housing, others believe that rent control forces people into public housing, still others believe that rent control has nothing to do with it.
