I think every older generation fears the younger as being unruly, dissobedient, uncaring, etc. They seem to forget they were the younger generation at some point doing their own thing making stupid mistakes, but somewhere along the line they grow up and become the middle and older generations and have learnt from their lives.
Having lived life and made stupid mistakes [and survived them] they may want to impart this knowledge on a generation who don't want to listen and who want to make their own mistakes, I suppose this generally get looked upon as the older generation trying to help/ take care of the younger folks who are dissrespectful and don't want to listen.
Humans and humanity haven't changed much, the world hasn't really changed that much, peoples wants, needs and desires haven't changed much. We like to think we are running things and calling the shots but by and large things remain the same, perhaps different ways of doing the same things and different technologies turn up but people all live, learn, eat, sleep and die.
