Why did living spaces/streets become messy?
I would assume that is pretty easy to answer why upkeep was not paid on several levels but am curious if there are more subtle or harder to grok answers to that?
If memory serves, even the elderkin's living-quarters (the radio-handler, the piano teacher/principal) seemed cluttered as the story wanes... and of course, the protagonist/narrator's home went full-blown cat-lady/hoarder mode by the end.
