Sometime it seems to me that some kind of personality cult is necessary for every well working totalitarian society, simply because this figure/idol, the suppressed people can look up to, is required by them. A sheep needs a shepherd and a sheep wants a shepherd.
What I mean is that people are (if concious or not) searching for someone leading them, may it be because they are too weak to find their way in life, too lazy (like e.g. Kant said) or want to serve a higher purpose, which is shown to them by this idol, this "fixing star".
It happens very quickly that masses follow someone, who seems to know, where the right path is going to. Where this person leads them to is up to him and his responsibility.
That effect is shown in cases of various religious leaders, kings and emperors and has been misused way too often (Hitler, Stalin, Kim Jong Il, Mao Zedong ...).
But all these people have been benefiting from this effect, the uncertainty people feel, when they realize (concious or not) that they are blind and don't see "the greater thing", though I am certain that there are a few, who have overcome this limitation, act fully responsible and concious... and sometimes they are lead as well...
Without a personal cult, a figure in front, a teacher (e.g. Father) an abstract system/ idea does not appeal to most of the people, because most of them cannot really imagine it.
But if there's someone, who seems to be trustworthy (or they have learned from early ages that this person is supposed to be...) and explains it to them, most will obey and follow...
not because they believe in the idea, only a small part really will...
but they will believe in the leader...
I guess it would have been very interesting, what would have happened to Hitler if he wouldn't have been able to start the war.
Comparing it with Spains fascist leader Franco, you can say that the whole system/cult build around him would have broke down soon after he died, simply because the leading figure, the fixing point was gone. After Franco's death democracy, even monarchy returned to Spain.
To avoid this, North Korea's dictator Kim Jong Il is initiating a new personal cult around his son Kim Jong Un as long as he still can, so that there would already be a new figure representing the state, if he'd die. And the Kim family would stay in charge.
And that's also why Dupont needed to hold the figure of Father alive, the people needed to belive that he was still there... because they would not have trusted Dupont most likely. ;D
I don't think that Hitler would have found someone, who would have been "believable"/"convincing" enough to take his place.
The system probably would have fallen soon after...
silently and completely without incidents... ;D
And another example: Every Exil-Cuban is waiting for the death of Castro, and most likely everything will change after his death, simply because the "shepherd", the fix point would have been gone.
Totalitarian systems rise and fall with their leading figures and therefore it's hard for them to survive more then one or two generations. So there's always hope...
