There's a lot of discussion about George #Orwell and #1984 around, and i'm happy.
Although I agree that both #AnimalFarm and 1984 were clearly a critique of the Soviet Union, I would also claim that they were not direct critiques of #Communism as such & definitely not critiques of Marxism.
What these excellent pieces really were, were critiques of concentration of #power. That the object of power always becomes power of itself. Noble aims become corrupted & corruption can be framed as good.
