And yet someone had to make toy sand-shovels for the world. What, in a just society, could ever induce someone to do that sort of work? Should all youths be conscripted to work in factories for a year? Should plastics-factory labour be reserved for the punishment of white-collar criminals? Finally I decided that salaries should be determined by a factor that averaged the arduousness, tediousness, futility and imbecility of a job. The richest people in the world then would be coal miners. Injection-moulding machine operators or tenders would fly to work in their own planes, and competition for such work would be stiff. Having had the experience, I would be quite content to be poor.
