Although they all had official positions with the Officials, the ideas of an era were unique to that era.
As in the earliest times before the disaster, the focus was on dedication, which is often heard in the broadcast propaganda: "I am for everyone, and everyone is for me."
After some time, that saying changed to, "It doesn't matter if it's a black cat or a white cat, as long as it can catch mice, it's a good cat."
Then it became about how young people needed to suffer more, so they could enjoy prosperity later.
After that, the notion shifted to having a wolf-like nature, not caring about personal gains and losses, and considering things from the perspective of the group.
Then came the first person to counter the rat race, who uttered the most classic phrase that you only do as much work as you're paid for; at this point, being a slacker was no longer a derogatory term.
The different eras result in each generation's mainstream thoughts being dissimilar.
