The aim of this article is to investigate the general and special obligations of parents with respect to the shaping of consumption habits, from a liberal egalitarian perspective. The article argues that, in virtue of them being well placed to shape the next generation's consumption habits, parents have a duty of justice to prevent their children from developing expensive consumption habits in order to enable them to leave their fair share to others. In virtue of the special relationship they have with their children, parents have a duty of care, and this may also require parents to prevent their children from developing expensive consumption habits. Then the article discusses whether and under which conditions these duties hold in unjust circumstances, where a consumerist ethos is predominant and where other parents and educational agents do not collaborate effectively.
