I can't help but think of the telephone sanitizers from planet Golgafrincham in Hitchiker's Guide to the Galaxy whenever someone makes the claim that a class of jobs is useless. These tales of impending doom allowed the Golgafrinchans to rid themselves of an entire useless third of their population. The story was that they would build three Ark ships. Into the A ship would go all the leaders, scientists and other high achievers. The C ship would contain all the people who made things and did things, and the B ark would hold everyone else, such as hairdressers and telephone sanitisers. They sent the B ship off first, but of course the other two-thirds of the population stayed on the planet and lived full, rich and happy lives until they were all wiped out by a virulent disease contracted from a dirty telephone.
