It is possible that members of a family get separated due to education at a different location. Due to the education environment or new friends, one may become more distant to their own family members.
As the children learn new things that their elders at home have not learned, it is possible that they may develop undesired ego or superiority complex. They may not respect their parents or grand parents with respect.
Educated families live in general as micro families. Long standing combined families have been lost. Because young persons are more educated they want to fly off to far off places alone to live and make their own life. That may not be the desire of the entire family.
As one is educated and has a number of gadgets, computers etc. one may reduce one's communication with own family.
