What does Hesse describe as the “expression of rich people?”

From the text:

His face was still smarter and more spiritual than others, but it rarely laughed, and assumed, one after another, those features which are so often found in the faces of rich people, those features of discontent, of sickliness, of ill-humour, of sloth, of a lack of love. Slowly the disease of the soul, which rich people have, grabbed hold of him.
