In Arthur Miller's "Death of a Salesman", how does Willy's memory of his father's funeral compare with his own funeral?

In Arthur Miller's "Death of a Salesman", Willy describes
his father's funeral as a symbol of his popularity.  He says that people came from
everywhere.  He was such a well-liked and successful salesman that his business contacts
filled the funeral parlour.  However, Willy who thought he was also as well-liked and
who also assumed he was a successful business man has an empty funeral parlour.  When he
is planning his suicide, he thinks that people will come from everywhere, just as they
had with his father.  The reality, however, demonstrates that Willy had no friends and
was disillusioned his entire life. This is the true tragedy of the
play.
