If you look at the book Feed, and then compare it to the book Brave New World, you find a lot of similarities. One similarity that really stuck out to me was the advancement of technology and how it is making their worlds worse. In Feed, the advanced technology was causing the people living in that world to resort to wearing masks and special clothes when they went near the ocean, they didn't have a real sun or clouds, they didn't even have real farm animals. Everything was artificial and it was killing them. In Brave New World, the technology they use is for education purposes. They are taught from birth what social rank they will be, what they like, and what they don't like. This basically tells them what to think and do. They don't really have any mind or opinion of their own. If they don't like something or if they want to escape reality, they take a soma and its gone.
