Not to be super English major about it, but Animal Farm was NOT an “anti-revolution” story. According to Orwell, it was inspired specifically by the Russian Revolution that led to the Stalinist regime. The story of animal farm is essentially what happened to the Russian people: they had a revolution against the tyrannical ruling class, only for the very people who had promised them freedom to turn into tyrants themselves.
The moral of the story is not “don’t have a revolution,” it’s that you should always be suspicious of those who promise you this utopian idea of freedom while still aiming to maintain power. The pigs never wanted to actually make everyone free, they just wanted to be the ones in charge. The novel details every small instance of the farm sliding further and further into fascism until it’s too late for anyone to do anything about it.
And 1984 doesn’t have much to do with communism at all. It’s about totalitarianism and fascism. There’s nothing pro-capitalist about the book. A totalitarian government like Big Brother’s could exist in either a capitalist or communist society. The point is the control they have over their people, and how important the flow of information is to that control.
George Orwell literally risked his life fighting fascists, so I think it’s pretty unfair to reduce his books to “anti-commie” propaganda. He was intensely critical of any state that maintained too much power over its people, and at the time, one of the worst examples of that was the recent communist revolution in Russia, which deposed a monarchy to install a dictator in its place.
