I would argue that classrooms are propaganda to convince us that we are not in a prison. We have a better illusion because we have a, "choice" to leave our cage, to get into a rolling cage, then work in another cage. To further this analogy, how many people wait in their rolling cage to go to another cage where they can run on a hamster wheel. In prison, people get 3 square meals, daily hot showers, and 1 hour of rec, and access to healthcare. Most of our senior citizens don't have it that good.
