Abstract
The main purpose of this article is to consider the post-industrial society in the trend of maturity of various factors, such as social structures, social values, personalities, and so on. First, we focus on the maturity of society and individuals in details. In this study, we would like to describe the future image of our society. Second, we formalize some aspects of labor system(labor demand-supply system, labor organization system, etc.), and discuss the possibility of maturity concerning the change of its system. In this case, it is important for us to predict and consider the future economic condition. Third, we relate the concept of 'quality of life' to those of 'quality of working life' and 'symbiosis'. Fourth, we consider the flexibility of labor system in the post-industrial society, and point out the importance of the change of labor organizations. Finally, we discuss the viewpoints of human beings and social system in relation to our labor system. We should recognize the degree of freedom in our society to build the 'quality of life society'.
