America's class system is perennially the elephant in the room. The subject of class was last tackled best by Paul Fussell in his book Class: A Guide Through the American Status System. But that book was released in 1983, and things have changed a lot since then.
Frank begins his book with a chapter focusing on the people most of us will find most relatable throughout the book: butlers and personal assistants. A butler school in Colorado trains its students in the exacting art of butlery (butlering?) and household management. New graduates of the school typically land jobs that start at between $80,000 and $120,000 per year.
