Earlier quoted context omitted.
In Japanese schools, the kids are the ones doing the cleaning. Not just taking out the trash, but cleaning the blackboards, mopping the floor, tidying up the desks, cleaning the bathrooms, etc. The reasoning isn't to save money, however. It is precisely to teach them there's no such thing as work that is beneath them.
The idea of replicating this in a modern office is quite the amusing image. It strikes me as both true and false: - no job is truly beneath me, and sometimes I have to wade into the weeds so better be prepared - it's also a way to just get essentially free or cheap(er) labour by increasing the duties of those whose time would be better spent elsewhere.
Do you think the cleaner is paid more than the other workers???
