Résumé : Based on findings that some young people from well-to-do socioeconomic circles nowadays encounter difficulties facing up to their own adulthood, the authors share some considerations on the influence of intergenerational transmission on the symptoms and obstacles identified in the empowering process. Working from clinical studies, they connect such difficulties with family traumas, loyalty phenomena and unspoken family history. The transgenerational dimension emerges as one significant factor from among the many likely to impede autonomy. Indeed, it threatens to slow down the possibilities of reworking the family system's organization, which constitutes an essential feature of the securisation process for young adults and thus their commitment to a life plan. Belonging to a privileged class appears to weigh heavily on this transgenerational dimension.
