Separation

One element of Brave New World that really intrigued me was the use of the Alpha,Beta, etc. classes. It seems so far that almost every novel I've read that is placed in a dystopian society involves separation of certain groups of people from a relatively different group. This could just be me, but I feel like there will always be a connection to this segregation when discussing dystopian societies,and that is in part of what causes the problems that ultimately lead to the downfall of that society.
