As Étienne de la Boétie
put it, even dictators rely on the consent of the governed.
Tyrannical rulers must be generous enough to their closest advisers, military, and secret police to avoid having guns turned back at the ruler.
But even a small population of enforcers cannot keep the people under the ruler's thumb if they don't like the arrangement.
Ever notice how every ruler of a one-party state has his (always a male!?) picture all over the place with enthusiastic slogans and proclamations of the ruler's beneficence? Why spend the time and money if the ruler didn't care what the people thought about him?
And no matter what type of government you have, the schools always serve students the state-sponsored Kool-Aid. The young are brought up to revere their leaders (especially the founders or first anti-Colonials who brought the current government into power after the last assholes screwed everything up). Students learn to appreciate and respect the way the government provides for them through thick and thin, even if you are not allowed to openly speak about the negatives that inevitably arise in a society of fallible human beings, or even if the economy fails to provide for basic needs.
No matter where you live, and what type of government you live under, it will not last forever. . . One day, after the current assholes have screwed everything up, a new form of government will come to fix it. . . until they become the assholes that screwed everything up (in about ten generations, give or take).
