Character growth and plot development are two different things.
Most people are used to character growth and the plot staying somewhat the same. And in reality, characters in most shows don't grow, they just change. In many shows characters change to shift around the story as it moves but people mistake that for character growth.
It's a more nuanced thing to watch adults whose personalities have been formed by their upbringing and surroundings have to deal with the world around them as it changes.
Because in reality, most people beyond a certain point don't change. They either adapt or sink, but they don't actually change. Especially if nothing about their lives has ever required them to change or learn the survival skills to adapt. All of Logan's kids grew up living a life where the world revolved around them. We met all of them when they were at least 30, if not close to 40 or 50 years old in the case of Connor. And not only were they grown in age, they were spoiled and privileged, and lived in a world where everything they did, wanted and lived for revolved around their father. So essentially, the living room family moments of trying to get your dad's attention when you were 10 never stopped, they just put on suits and started cursing. So they never had to grow up, all they did was age.
So all that was going to happen with people like that is the world was going to change and their circumstances were going to change, but they were unable to adapt to it because of their upbringing. They were wholly unprepared for life because they had no lives. They weren't whole, real people.
The only person who saw it for what it was, and was trying to either change or change them, was the man who didn't grow up rich and had to learn to adapt, grow and pivot his whole life.
Then he died, leaving a bunch of planets without a sun to revolve around.
And the only person who did truly grow was the one who didn't grow up like they did, so he had to adapt or die.
And he ended up running the company.
How else was it supposed to go?
