The chapter "The Age of Social Transformation" by Peter F. Drucker examines the profound social changes that have occurred in the 20th century, particularly in developed free-market countries. These changes include a shift from an economy based on labor and raw materials to one driven by knowledge, a rise in inequality based on knowledge, and a transformation in the role of government. The author highlights the disappearance of traditional classes such as farmers and domestic servants, and the rise of industrial workers, who became the dominant social force by the early 20th century. However, the decline of industrial workers and the emergence of knowledge workers pose significant challenges, including the need for continuous learning and specialized skills. The chapter also discusses the impact of these changes on society, including the role of education, the importance of teamwork, and the changing nature of work and employment. Drucker argues that the knowledge society is characterized by high specialization, mobility, and a focus on continuous learning, and that management will play a central role in this new social order.The chapter "The Age of Social Transformation" by Peter F.
