Sociology of Generational Differences?

I've been discussing with my father causes for social problems in Japan. First, school-age Japanese kids and adolescents who refuse to go to school and seclude themselves in their own rooms. I hypothesize that those men who sustained the rapid growth of the Japanese economy in the 1960s were not good fathers; they spent little time with their kids, so that their kids, who are now in their 40s, are not very good at parenting their own children, either.

Second, prefectural bureaucrats who are ineffective and inefficient, obstructing reforms that are (urgently) necessary for Japan. Here, I can use a generational perspective once again. Through the 1960s to early 90s, businesses trained university graduates on their own; they did not expect that those graduates received kinds of education that could be utilized for "real" work. (Indeed, Japanese universities have been the place where many students who were exhausted after entrance exams took break.) But, unlike businesses, prefectural governments didn't train university graduates properly. And whatever Max Weber said about bureaucracy, I think that prefectural bureaucracy is an apex of inefficiency.
