“At this moment, there’s someone training for your job. He may not be as smart as you are–in fact, he could be quite stupid–but what he lacks in intelligence he makes up for in drive, reliability, consistency, and price. He’s willing to work for longer hours, and he’s capable of doing better work, at a much lower wage. He doesn’t ask for health or retirement benefits, he doesn’t take sick days, and he doesn’t goof off when he’s on the clock.”
