No. In 'Animal Farm' the pigs become elites. All other animals toil to support them. The pigs were the object of the phrase from the book "All animals are equal but some are more equal than others."
I think it was during the Spanish Civil War that Republican propagandists coined "Fascist Pigs" to refer to their nationalist enemies. The American left probable adopted it from them.
'Animal Farm' is well worth reading.
