What is of "freedoom" in Death of a Salesman ?

Linda's last two lines in the play are directed toward Willy (in his grave). In these two lines the couple's freedom from debt comes to the forefront. Throughout the play, we see Willy trying to hang onto his job, get another job, ect., but all he really needed at this point was enough to get by..... everything else had already been taken care of.

LINDA: I can’t understand it. At this time especially. First time in thirty-five years we were just about free and clear. He only

needed a little salary. He was even finished with the dentist.

LINDA: Forgive me, dear. I can’t cry. I don’t know what it is, I

can’t cry. I don’t understand it. Why did you ever do that? Help

me Willy, I can’t cry. It seems to me that you’re just on another

trip. I keep expecting you. Willy, dear, I can’t cry. Why did you

do it? I search and search and I search, and I can’t understand

it, Willy. I made the last payment on the house today. Today,

dear. And there’ll be nobody home. (A sob rises in her throat.)

We’re free and clear. (Sobbing more fully, released.) We’re free.

(Biff comes slowly toward her.) We’re free... We’re free...

Note: A huge portion of Willy's debt had be taken care of with his insurance money. Thus, the "worth more dead than alive" had definitely stayed with Willy.

Also, I'm not sure about Linda, but there is an allusion that the family (particularly the boys) are free of their father and the harm he caused them.
