All pure get out of my seat.
Yip, it's the other way around. It's your generation that has "get out of my seat" syndrome (and get off my lawn syndrome). Those seats belonged to the next generation of pilots. .as they always had.. but it was the boomers who told the rest of us "get out of my seat". And then had the balls to sit there and act like they were entitled to it because they think they were the only generation who'd "paid their dues". Try spending 7 years in the right seat at a regional. You can tell me all about the guys who sat sideways for 10 years but they weren't making regional wages back then.
Air Traffic Controllers retire at 57. Why do you think that is? Because they have to think quickly and stay sharp. And you lose that in old age. It's part of the natural cycle. Accept it.
