Intergenerational justice cannot be young versus old or old versus young. And often the age groups in the middle are forgotten. The aim must be to preserve a Europe that is worth living for all people. Intergenerational justice should focus on the opportunities that rising life expectancy brings, and take action to use the years gained - individually and for the community. Especially in the areas of mobility, urban and municipal planning, the interests of children and young people are often very similar to those of older people, e.g. in the accessibility of destinations by public transport or a good footpath infrastructure, decentralized shopping facilities, zones to linger and meet. And the sandwich generation has to be brought out of the hamster wheel. It must not fall directly from child-rearing into the care of the older generation. Women in particular suffer from the unjust distribution of care work throughout the life course. Generational justice also means gender equality and recognition of care work as an essential contribution to a functioning, solidarity-based society.
