Fussell goes on to state that the American class system is a very ``murky'' subject and that class in America is seen differently depending on your class status. So that, the lower class (prole-short for proletariat) sees class as based upon the amount of money you have. Whereas, the middle class focuses on the type of education and job that you hold. While, finally, the upper-class sees it as a set of values, styles and tastes.
In analysing the class structure in America, Fussell concentrates mainly on things that people can avoid (were they conscious of it.) In other words, Fussell will concentrate on the choices made by the class members, rather than, rely on things that they cannot avoid (such as race, ethnicity, religion, politics &c.)
