Animal farm repeatedly, the animals sacrifice themselves in order to complete the windmill, only to see it destroyed time and again. what, if any, symbolic role does the windmill play? how do you account for the pigs' insistence that it be built and re-built?

The windmill symbolizes a considerable measure of things. The mill is utilized as abusing creatures like Boxer for the pigs' pick up. The windmill's unique goal was to make life less demanding on the homestead yet Napoleon transformed it into a methods for social molding and misuse. Napoleon likewise utilizes the windmill to control Snowball. As the first creator of this factory, Snowball needed to truly make less work for the creatures on the ranch. Rather Napoleon makes Snowball the substitute for its first obliteration. The Pigs start to receive the rewards from the windmill while alternate creatures are liable to significantly more drudge and hardship. The incongruity is that a similar factory, that once symbolized opportunity and liberation for the creatures, soon symbolized subjugation and disloyalty. As a moral story; the windmill speaks to industrialization of Soviet Russia. It was a mechanical upheaval that, similar to Animal homestead, was not shared by the entire populace. Re-constructing the windmill speaks to the innocent unresponsiveness of the creatures that indiscriminately take after the pigs' requests and trust them regardless of their untruths.
