In animal farm, how does Orwell use the character of old major to highlight ideas about inequality?

Major claims to “understand the nature of life on this earth as well as any animal now living” (28). Months after his death, the pigs disinter his skull and place it at the base of the flagpole beside the gun. Major symbolizes two historical figures. First, he represents Karl Marx, the father of Marxism.Major spreads the message of a Socialist Utopia where all animals work and share in the fruits of their labour.
