I'm listening to the audio book for my own education and while parts are interesting, my knowledge of Jewish history is so limited that much of what she writes goes beyond my head, and therefore makes it difficult for me to follow along. I've never stopped reading a book midway before but I think this book may be the first. So I'm asking for a summary to grasp the essence of what she is seeking to communicate with her book.

For example, she had oftentimes referenced the "Dreyfus Affair" and its role in identifying Anti-Semitism and pushing forth the political identity of the Jews. Until I separately studied the Dreyfus Affair, I had no context to grasp her message. So perhaps a summary that I can maintain in the back of my head as I read the book would help guide me. I'm not yet halfway through.

Particularly I'm interested in grasping her analysis of how Jewish society became such a separate and disparate entity from nation-state identity and also how they evolved into the role of money lenders. Since I've only gotten midway through the book, any further summary of the rest of the book would be appreciated.
