I would be quite interested to know how it is that expanded families perform when it comes to the enculturation and socialization of children. It would, in some ways, like your ideal incorporate multiple adults taking key roles in the lives of the young. However I would prefer a more stable location where they share residence. I am quite fond of your idea about introducing children to cross cultural experiences as this can show a lot of promise. My approach of course is hardly a novel one and has been argued for in Euroamerican culture for some time and to various degrees variants have been present in other cultures. I would be interested in how it functions in contemporary 'Euroamerican society'.
