Letterman was always a faggot, he's like Conan. a bunch of dipshits gave him unearned good will because of how they got fucked over by NBC. You'd be surprised how based and redpilled people said Tim Schafer was a decade ago because he got fucked by Kotick. Its literally the exact same thing here. Conan banned norm from his show while Leno offered to let him co-host his tv show. Norm&Jay's garage they would have changed the name to.
Letterman hasn't been funny since the 90s. Fun Fact his head writers joined Opie's show after Cumia left, yet because there isn't any unearned goodwill there everyone admits how much the people behind Letterman's show fucking suck.
you aren't completely wrong. most grandkids will never understand the legacy of what their grandparents made, its why once Chris kicked the bucket we got the amazon series coming down the line, just in general outside of the extremely rich, who usually can force it through giving their descendants jobs at companies, most grandkids won't know or care about their grandparents legacies unless they were raised by them.
So the estates are led by people who care more about heckin niggerinos than their own flesh and blood.
