Sounds like we had similar experiences. It really is infuriating. I try not to think about it too much. They wonder why I don't ever talk to them but then when I try and explain why they don't want to hear it. Whatever. Had a grandpa recently pass away and I think I cared more than he did. He was retired, just sat around doing nothing all day. Never seemed to care how his own family was faring through life. Just up and died one day without telling anybody he was sick. Didn't pass on any wisdom to anybody, didn't leave anything behind. I don't get it I don't think your theory about using generations against each other is insane. They seem really determined to keep millennials out of politics.
