Answer: Self-worth is something determined by someone's own mental health and restraint. Sometimes owning something does not define how you veiw yourself. For example if you owned a broken stuffed animal as a childhood toy, it wouldn't reflect your occupation as a billionare. It depends from people to people.

Answer: I don't know of the book you read, but..
Authors use historical times and revise them in such a way it's believable, immersive, and informative. They make sure their use of history isn't changed into an outlandish fashion to fit the time it's set in. They usually do this because you can't go back in history and show them what happened, so you must create a fictional yet historical piece to preserve the time.
