Death of a salesman

Plot - Willy's son comes home after working out west, Willy and Biff argue about his (being Biff) lack of a career, Willy then finds out Biff has always loved him and then kills himself.
Historical context - From the context one can infer that the time span was around the early to mid 1900's. Willy talks about how $10,000 a year is a lot of money and only taking home $60 a week would be enough to live off of. Present day, even $10,000 a year would barely be enough to live off of, and $60 a week might get you enough food, but certainly no shelter. After finding about when this play was written (1949), one can tell this was written shortly after both world wars.
Sequence - When the play starts, Willy has already been in a car crash and Biff has come home from working out west on a ranch. As the play progresses Willy and Biff are constantly arguing and Willy is often found talking to characters that aren't really there. The play jumps around a lot from in-the-moment flashbacks to present day. This type of storytelling is confusing but also helps the reader to understand what happened before "now."
Narrative - There is no narrator, only the characters and their dialogue.
Characterization - Linda is portrayed as a sweet and loyal wife who is extremely patient with her husband although is not always kind to her. Her character never falters. Even when she discovers Willy is trying to kill herself she does not do much but try to prevent it because she wants her husband to feel like he still has his dignity and she does not know.
Charley is a giving man and is always there for Willy even though Willy does not seem very appreciative (calling Charley disgusting and not accepting his job offer). Charley is a smart man and understands that Willy will not take his job offer due to pride.
Biff at first is a proud, confident boy who seems to be capable of anything. Later we find out that he sees himself as worthless and someone who won't ever amount to much. Throughout the whole play Biff is convinced he is something he is not because he wants to make his dad proud. In the end Biff admits to everyone who he is.
Willy is hard headed and cannot accept failure (possibly because he himself is a failure and doesn't want to same for Biff). Willy never accepts the fact that he was never successful and is fully convinced that Biff is something more than he truly is.
