In this major study of poor working women in a third world urban market, the authors expode several assumptions held by agencies working in developing countries. By talking with poor women about their life histories, they found, for example, that there is neither individual nor intergenerational mobility; that poor women are the children of poor parents and that their own children can hardly even hope to move up to a factory job, let alone a white-collar job. They also find that this group of marginal poor women is increasing and not, as current wisdom would have, being absorbed into the modern sector of the economy.
