Supposedly the task or interest of Delta is not to stabilize any system, is actually to perfect society through technology and morals (according Gulenko). Is not about systems but individuation. Is about completion, perfection and rest. And according Strat is about reaching self perfection, teaching others and trying to get a state above commonality, to look for trascendence.
Delta leads old age, pushing for a more relaxing, self-focused, live-and-let-live morality. Dramatics are suppressed for calm, relaxing activities, and there is the desire to stabilize the system, particularly as the wealth people have developed over their lives depend on the system they used to accumulate it.
