What was the primary reason that a fourth sector of the economy was created?

The primary reason for the creation of a fourth sector of the economy, often referred to as the "social economy" or "solidarity economy," is to address societal needs that are not adequately met by the traditional private and public sectors. This sector emphasizes social impact and community well-being, prioritizing values such as cooperation, sustainability, and social justice over profit maximization. It encompasses various organizations, including cooperatives, nonprofits, and social enterprises, aiming to create economic opportunities while fostering social cohesion and environmental stewardship.
