In the nuclear family the child is confronted by only two adults contrasted by sex. The tendency towards polarization is unavoidable. The duplication of effort in the nuclear family is directly connected to the family's role as the principal unit of consumption in consumer society. Each household is destined to acquire a complete set of all the consumer durables considered necessary for the good life and per caput consumption is therefore maintained at its highest level. In sex, as in consumption, the nuclear family emphasizes possession and exclusivity at the expense of the kinds of emotional relationships that work for co-operation and solidarity.
