How were the pigs selfish/What showed they are overpriviledged than others?? Provide evidence from text and elaborate

The pigs in "Animal Farm" took over the farm. They changed the rules to benefit themselves, and as the story went on, they took advatage of those around them and destroyed anyone trying to stop them. One example of this would be the apples and milk they deliberately kept aside for themselves.....

`Comrades!' he cried. `You do not imagine, I hope, that we pigs are doing this in a spirit of selfishness and privilege? Many of us actually dislike milk and apples. I dislike them myself. Our sole object in taking these things is to preserve our health. Milk and apples (this has been proved by Science, comrades) contain substances absolutely necessary to the well-being of a pig. We pigs are brainworkers."
