primitve societies and their modern counterparts

If we compare the way of treating children in non-industrial, primitive countries where worklife and family life was like the same and where families was very big including all the relatives with countries where family and work have a clear boundary, we can see many differences and all they are because of different values, norms, aims and very important- culture. As Ruth Benedict said in her work 'Patterns of culture': "If we are interested in cultural processes, the only way in which we can know the significance of the selected detail of behavior is against the background of the motives and emotions and values that are institutionalized in that culture". And to understand some maybe strange for us rules and values in culture we should learn it as a whole and try to accept and understand it. In some countries for example it is acceptable and common that children start working from their childhood as they should thinki about their future and help parents, in other countries girls in families already in childhood (8 and older) get married and if they don't want, there are rules which they can't break. While in their modern counterparts, children have less bad thoughts and don't think about different domestic problems, their childhood might be seen happier in comparison with primitive countries. While this opinion is not right, because in different countries people understand happiness and good life in different ways so i can't say  exactly that in modern societies children have better life.
