Japan is in the grip of an elderly crime wave

6. Margaret Atwood has a similar story in her short story collection: Stone Mattress.

In a collapsing society where there is no work. People seek shelter in gated communities where they are assigned an apartment and a job that they share with another person. In six month shifts they rotate between the job and jail. When they are in jail the other person inhabits their apartment and job then the two people switch position. There's much more to it than that, but this is the upshot.
The entire collection is about dystopian future and is brilliant.
