The article examines the rise of 'full-time children,' defined as individuals who identify their primary role as being a child rather than pursuing conventional jobs. This trend is increasingly common among younger generations, particularly in advanced nations facing challenges in achieving sustainable growth and securing resources for future generations. The book titled 'Full-time Children' highlights how societal changes have led to this new identity, where individuals may live with parents or independently but focus on family responsibilities instead of traditional career paths.

A singular focus on full-time parenting has been attributed to economic and social factors, as discussed by population expert Professor Jeong Young-soo of Hanyang University. He connects the rise of full-time children to global trends and the pressing issues faced in societies such as Japan, where the '8050 problem' illustrates the struggles of aging parents supporting adult children. The piece underscores the serious implications of changing family dynamics, where traditional roles are altered due to financial strains and shifting socio-economic landscapes.

Yet despite these challenges, the book proffers a more optimistic perspective, suggesting that the existence of full-time children could signify a resurgence of family welfare systems assisting in caregiving roles. This renewed family dynamic could also serve to unlock financial resources previously tied up within households, provided that appropriate job opportunities and systems support these individuals. The discourse encourages a reevaluation of the role of full-time children in contemporary societies, suggesting that embracing this identity may lead to greater potential for family cohesion and support amidst economic realities.
