what does Arthur Miller say about the American society in the book "Death of a salesman"?

Answer 1

It's an existential play that shows where there is ambition, there is tragedy. One can read it as a criticism of the American Dream.

Answer 2

Biff and Happy, it seems to me, symbolize a self-absorbed generation who benefit from their father's hard work but have no appreciation of it or him. The society they represent is demanding and thankless, burdens that weigh heavily on their father so that he feels like an unproductive failure, and, feeling this way the low-esteemed Willie Loman takes his own life.😢
