The issue is addressed whether assistance to persons in need can be left to the ‘family’ and the ‘community’. In that case people depend on their social networks. The support a person receives through a given network of social ties is examined. However, ties are diverse and subject to change. By means of a model of the dynamics of social ties, the conditions for adequate private support are analyzed.
