I mean you can call yourself that if you want, but no, we don't need a special name for your occupation / stage of life / population density of your place of residence configuration because everyone's already used to people they consider paradigmatically similar to yourself coming into their lives and workplaces.
Your world view is now predictable and known. Your future is not a wide array of endless possibility. Your potential and its course have been approximated with an acceptable degree of certainty. You're not part of the new and exciting or terrifying winds of change anymore. People know what to expect from you. You haven't merely worked for a living within the system, you became and now are the system. When the young reach the age of adulthood and come out to the world to claim things they feel entitled to, today it is sometimes you who holds the keys that determine if they get it or not.
Things would be different if you were a centennial (millenials are so passé), of course, but even if you attempted to rebel against your role as a system perpetuator, you'd just be another drone that has been adequately enslaved like the rest of us responsible workers, voters and citizens, only you'd be having a mid-life crisis.
But it's not all bad. At least we can laugh at their vocabulary and tell them a thing or two about "how we used to do it back in the day" while they doomscroll.
Hope you have a great week, fellow middle-aged drone! :)
