Be industrious. There he was, industrious brother, clever salesman, winning the business for Willis Gann and they got jealous of his success.
Squealer is a character in Animal Farm by George Orwell, a pig who serves as the main minion of Napoleon and the tertiary antagonist turned anti-hero. Squealer goes around telling lies to the other gullible farm animals to cover up and or/justify Napoleon's atrocities and convince the animals to stay loyal to him.
Around the middle of the book, Napoleon and Squealer start altering the sacred seven commandments of Animalism to serve their selfish interests, and Squealer insists that the commandments have always been that way, and their memories are mistaken.
