What message is Walter conveying when he says to Ruth, “You tired, ain’t you? Tired of everything. Me, the boy, the way we live – this beat-up hole – everything.” Is this statement really just about Ruth, or something more?

I think that Walter is talking about himself with this statement, as much as he attributes it to Ruth. Both Ruth and Walter want more... more for themselves, more for their family. Security is important, as is being able to make the bills and provide for a child. They both work hard, and they're both tired of feeling like things never change.... like they cannot get ahead. Sounds like a lot of families today....
