“Take a simple pocket pen, so cheap that they are given away as advertising. Back of it lie several sorts of chemists, metallurgists, synthetic polymer experts, mechanical engineers, extrusion presses, computer programmers, computers, computer technicians, toolmakers, electrical engineers, a planet-wide petroleum industry, five or more sorts of mines with mining engineers, geologists, miners, railroads, steamships, production engineers, management specialists, merchandizing psychologists—et cetera to a splitting headache. It is impossible even to list the myriad special skills that underlie even the most trivial trade item of our enormously complex and interdependent industrial web.”
