The accusation that those who address matters of class are instigating class struggle is an old one. It stems from the assumption contested in this book that class is not an issue with which we need to be concerned any more because we are living in a world where classes either have been abolished altogether, or in which the boundaries between classes have become so permeable that people can freely choose the class to which they care to belong. In recent history, the accusation of instigating class struggle has been leveled again against the Occupy Wall Street movement and its attention to matters of class, with particular regard to the difference between the 1 percent and the 99 percent.
