This chapter sketches the contours of a democratic ethics of youth policies. Drawing on theories of distributive justice between co-existing generations, I shed some light on the question of what counts as an adequate set of opportunities for the young. As illustrated by the example of lifespan sufficiency, I show that although abstract principles often give us a frame to set the terms of the debate, they fail to tell us precisely what the young are owed. To translate requirements of age-group justice into policy guidelines, we need to overcome important democratic imbalances in the representation of youth interests. I conclude by offering some potential democratic remedies to this intergenerational democratic deficit.
