Question of the Day

Why is it that Willy is the only "proactive" person in the family? The wife, Linda, seems to support him, but not really do anything to help him when he starts to slip off the rocker. The kids, while Happy is having some success, never really seem to be able to pull themselves off of their feet. I know that they are imprinted with this notion that your success rides on a smile and a polished pair of shoes, but at the end they seem to realize that this is wrong, and they still don't do anything about it. Why is this?
