They wouldn't have anyone. The person that wrote the software that they use to put their crap on their official web site had to have gone to college to learn how to write the software. The person that designed the computers that run Beth Hell most likely learned to engineer computers while in college.
Most of the infrastructure was designed by someone that learned engineering in college. Your electricity is generated by people that manage power plants--those jobs require college (and more so if they are running nuclear power plants). The buildings were designed, at least in part, by people that went to college. They needed licensed plumbers and electricians, who need college courses. Which they would have to do themselves (and risk having plumbing and electrical problems and fires).
Just about every chemical they use at Beth Hell was designed by people that went to college. From the inks that they use at the presses to the cleaning chemicals that witlesses use in their cleaning businesses are all designed by engineers, and they have college degrees. The plastics and metals in their presses, and everywhere else, were composed by people with chemical engineering and/or physics degrees. Meaning they would be left in the Dark Ages when it came to printing technologies.
And, I went to college before becoming a witless. Thus, they would not be able to use me for the Value Destroyer Training School. Nor would they be able to give me a billion simultaneous assignments after, use me to get their Critical Mass, and start the whole world in the Second Dark Ages. Looks like they would be up sxxx creek without a paddle.
