What's really interesting for me in Atlas Shrugged is the way people are going back to sound money by leaving the hyperinflationary fiat system. When I read the book, I thought that gold is just some symbol/metaphor, but not something important. Since then I learned more about the way money works and realized that it wasn't a metaphor at all, and I'm seeing how history repeats itself, and people haven't learned from the mistakes that were made 80 years ago.
