I was going to start out writing about how this book has lots to do with medieval times, however since I saw some other posts seeing that relationship I brainstormed a little and somehow thought of the last book, One Day in the Life of Ivan Denisovich. At first it might seem worlds away, the themes don't really match, and neither does the way in which the book is represented. But you look at how the prisoner's are treated (mindless objects) and how anything that makes you original eventually punished. It talked about how a certain prisoner had to hide his bible really well as it would be taken from him if people found out (seems awfully alike what might happen with Equality.) Any object that wasn't absolutely necessary had to be hidden from the guards, even things such as an extra layer of clothes were taken from inmates.
Once in the gulag (the forced labor camps describe in One Day in the Life of Ivan Denisovich) you are treated as part of the masses, nothing more, and sometimes even less. The only difference in Anthem is that you are treated with respect and kindness, and being treated as part of the masses has gone to a whole new level. Forget of being "I" or "me" you are now "we." We have gone there, we need food, we will do this. Even if you are alone, everything goes towards your fellow brothers and sisters, nothing for yourself. Same as Ivan, he is expected to work his life off towards a group of people he probably cares nothing about, and Equality has to follow a strict code forcing him to work for his community.
