A man may be a tough, concentrated, successful money-maker and never contribute to his country anything more than a horrible example. A manager may be tough and practical, squeezing out, while the going is good, the last ounce of profit and dividend, and may leave behind him an exhausted industry and a legacy of industrial hatred. A tough manager may never look outside his own factory walls or be conscious of his partnership in a wider world. I often wonder what strange cud such men sit chewing when their working days are over, and the accumulating riches of the mind have eluded them.
~ Robert Menzies - [Management]
