"I'm a dime a dozen"

In this video clip on Death of a Salesman, the character of Willy is attacked verbally and manhandled by Biff, who is like a raving, estranged caged animal, as he tries to make Willy understand that they are both only, "a dime a dozen".

Biff has had the blinding wool of the unrealistic American Dream removed from his eyes and is trying to tell his father that he has realized what was the cause of his failure and that his father needs to open his eyes also and face reality before someone is hurt. This is ironic because soon after Willy ends up dead.

Biff not only tries to open his father's eyes verbally, but also lays it all out before him, literally, when he puts the hose down on the table. Come to think of it the unknown amounts of carbon monoxide that he(Willy) was inhaling might also have been a contributor to his apparent brain damage. It also indicates that Biff was the only one in the family with a spine. Why didn't Linda as soon as she'd found out what Willy was doing take off the hose? Was it because she wanted Willy to be 'man' enough to remove it himself? This reason would have been ludacris because she would have been helping him kill himself (abetting and aiding).

And what is Happy's excuse? He was in his mind protecting his father from the rage of his brother, but in essence he was protecting Willy from the harsh truth. He and Linda were treating Willy as a child when really he needed to face the facts, no matter how harsh and cruel they seemed. They would have done him more good than evil.
