"So is a theory about human nature a discovery, or is it an invention? I believe that often, it is more invention than discovery. I think that ideas, like Adam Smith's, about what motivates people to work have shaped the nature of the workplace. I think they have shaped the workplace in directions that are unfortunate. What this means is that instead of walking around thinking that "well, work just is what it is, and we have to deal with it," we should be asking whether the way work is is the way it should be. My answer to that question is an unequivocal no." --
