“Today, America’s work force is divided into three parts: about 25 percent are the ‘smart people’ who are educated and also have special career skills; another 25 percent are the ‘walking dead,’ victims of mergers or technological change and [who] need to acquire new skills in order to change jobs or even careers… and up to 50 percent are the ‘techno-peasants,’ poorly educated adults with few if any special career skills.”
