"Man's entire life on earth has been a constant struggle to develop better tools so he could get more of everything. Early tools were so primitive that he could not produce much no matter how hard and how long he worked. When man had to use these stone tools, he was hungry most of the time. When he developed metal tools, man began to produce much more and to have more. When he developed power to run his tools, he did still better. In recent years man has begun to improve his power tools with the adoption of automatic controls."
Good Reading Rack Service, 1958
