With the advent of universal education, the world of children who are highly educated has little overlap with the world of their poorly educated parents. They are in contact with completely different levels of society. In particular, children who have high educations and high social status are not as good at staying at home and accompanying their parents as their less educated siblings.
教育普及後，高教育子女與低教育父母更形成了兩個難有交集的世界，彼此接觸的社會層面完全不同，尤其教育程度與社會地位越高的孩子，反而不如那「書讀不多」的可以留在家中陪伴父母。
