The family and the State are the best institutions for building solidarity, associations and the community can foster it. The exchange of time and money between generations works best when there is relative demographic equilibrium, so it should be acknowledged that intergenerational solidarity is, to varying degrees, currently under threat and subject to tensions concomitant with population ageing and formal and informal provision of care. Care policies impact the balance of responsibilities among the family, the community, the State and the market (Esping-Andersen, 2009) and should seek to balance the resources allocated to each age group.
