There's a pretty compelling quote from the first chapter of The Fifth Discipline:
"There is also another, in some ways deeper, movement toward learning organizations, part of the evolution of industrial society. Material affluence for the majority has gradually shifted people’s orientation toward work— from what Daniel Yankelovich called an “instrumental” view of work, where work was a means to an end, to a more “sacred” view, where people seek the “intrinsic” benefits of work. “Our grandfathers worked six days a week to earn what most of us now earn by Tuesday afternoon,” says Bill O’Brien, former CEO of Hanover Insurance. “The ferment in management will continue until we build organizations that are more consistent with man’s higher aspirations beyond food, shelter and belonging. Moreover, many who share these values are now in leadership positions. I find a growing number of organizational leaders who, while still a minority, feel they are part of a profound evolution in the nature of work as a social institution. “Why can’t we do good works at work?”"
