Individuality is commonly lost while searching for utopia. When that utopian state is reached it gets corrupted into a different from. A way that individuality is lost is everyone is equal, in Harrison Bergeron it is shown directly. In Animal farm it is shown everyone gets the same materials with a class system. A system that was caused by the corruption of utopia.
In utopia a common idea is everyone is equal, an idea that kills individuality. This idea has two conceptions; everyone is equal even their abilities, or everyone gets the same amount of everything. Harrison Bergeron does the primary one; everyone is the same and if you are above average you are handicapped, made to be normal. The problem with this approach is everyone is everyone is a clone of each other; so no one is an individual. The latter one is the approach of Animal Farm, everyone work and gets the same amount of food proportionately to what they need. Latter the pigs take more due to their false justification. The problem with this is it provides no incentive to work harder; it causes a discouragement of being an individual. This is due to that if you work extra you do not get a reward. This false justification leads to the development of a class system that corrupts the utopia.
Utopia always gets corrupted when or while it is achieved. The class system that corrupted Animal Farm was the pig getting bigger rations, the dogs get fed ok, and the rest of the animals get fed the minimum. This was caused by a totalitarian government after tasting power and Utopia. In real life Communism was supposed to be a utopia, but once Stalin and Putin tasted power Utopia was only for them and people they liked.
Utopia commonly removes individuality and once a leader tastes power and their utopia it is only for them. No attempt has succeeded to this day, if one comes I hope it does not take me away.
