Animal Farm by George Orwell
When the downtrodden animals of Manor Farm overthrow their drunken human master, Mr Jones, and take over management of the farm themselves, they believe it is the beginning of a life of freedom and plenty.
Everyone willingly works overtime, productivity soars and for one brief, glorious season, every belly is full and all the animals are equal.

Too soon, however, the pigs, who have styled themselves leaders by virtue of their intelligence, succumb to the temptations of privilege and power and as the ruthless elite start to take control the other animals find themselves hopelessly ensnared as one form of tyranny is gradually replaced by another.

(Rehearsals for Animal Farm)
The common animals are once again left hungry and exhausted, no better off than in the days
when humans ran the farm.
