Young ideals were one of the driving forces behind the social, cultural and political history of the 20th century. These days, there is no longer a place for the ideals that were once a young people’s prerogative. What has triumphed today is youth as an ideal and aspiration, i.e. young style and its culture. This desire, which has ceased to belong to an age-group, and the difficulties of access to full adulthood have rendered the borders between generational categories more fluid and opened up an injustice between generations. Many of the privileges that adults enjoyed no longer exist for the younger generation. The very large share that the idea of youth holds in the social and aesthetic market does not correspond to young people’s actual situation. In some ways, they are a robbed generation and, on the other, only they are fit to keep up with the times, which have been accelerating at breakneck speed. This dossier covers these issues.
