What does Death of a Salesman reveal about lower-middle class life?What does Death of a Salesman reveal about lower-middle class life?
Probably nothing. The class of the Lowman family has very little to do with Willy's delusions about himself or his occupation. Of course, if you are going to do a Marxist interpretation of the play, it must have some influence as class does in everything. If Willy had been in the middle-or-upper middle class, he may have a better change of making it into management and fulfilling his economic dreams, but that's a different play. If Biff had not gone to Boston, Willy might have had a better chance of fulfilling at least a part of his dreams (about his sons), but that's a different play as well.
Willies problems are about his own dreams and his inability to realize who he was, not about where he found himself on the economic ladder.
