The core of tyranny is Orwellian because there are people out to get power for its own sake. Still, Orwell's bitter pill has to be sugared with some Huxley before people are tricked into taking it.

Even in a Huxley's world, there would still be a shadowy elite running things. Hedonism was not an end (or an evil) in itself, but a tool to pacify the masses.
