I think if people in such High Control Groups realise it or not, deep. deep down they DO wish they were free.
This is how Cognitive Dissonance works, if thoughts about this begin to get nearer the surface, they are immediately pushed way back down again.
So everyone does want to leave, even if the closest they get to expressing it to themselves is something like "I wish Armageddon and the New System were here", that means they wish the regime they live under was over.
To criticise Hassan because his Books etc. assumes everyone wants to leave is silly, that is why they would be reading his books etc. !
And deep down everybody wants to leave, even if they think they don't, and think they are perfectly happy.
