Why does Sue Bayliss hate the Kellers in “All My Sons”?

Hate is a strong word..... Sue Bayliss certainly doesn't like the Kellers, but I don't believe that it's hate so much as suspicion. Sue realizes that the Kellers have a secret, something they keep to themselves. She is suspicious of their wealth, Joe's avoidance of prison, she resents Chris' influence on her husband, and she resents Chris' feelings about money, which seem to have influenced Jim's.
