I am of course quoting from a famous essay by Leonard Read, the economist in the 1950s, called "I, Pencil" in which he wrote about how a pencil came to be made, and how nobody knows even how to make a pencil, because the people who assemble it don't know how to mine graphite, and they don't know how to fell trees and that kind of thing.
Naravno citiram čuveni esej od Leonarda Reada, ekonomista iz pedesetih, naziva "Ja, olovka" u kojem je napisao kako nastaje olovka, i kako nitko ne zna kako se pravi olovka, jer ljudi koji je sastavljaju ne znaju kako vaditi grafit. I ne znaju kako rušiti drveće i takve stvari.
