At the beginning of act 2 , Sue complains to Ann about Chris's "phoney idealism".

Sue complains that her husband resents her for having put him through medical school, saying that "you can never owe somebody without resenting them." Sue says that Jim wants to do medical research and that Chris is the one who put idealistic thoughts of helping the world into her husband's head. She thinks that Chris makes other men feel guilty about their lives, while Chris lives on his father's business--she implies that this is not clean money; it is phoney idealism.

Thanks :P
