I don't know that I agree with that. 1984 described a fairly common type of state, the totalitarian oligarchy, which was beginning to use technology as a means to entrap and enslave its population. Huxley viewed a state that used pleasure to numb its citizens. Both models existes, although Orwell's totalitarian example was more common. Orwell was describing the communist states under Stalin, Mao and the like, while Huxley was describing decaying states as they devolved into decadence, like Rome or the Persian Empire. Voluptuarian states are rarer than totalitarian states, but they have existed.
