A common critical topic is to address various objects in the book and the characters' relationships with them, such as Rebecca's diamonds or the piano Amelia values when she thinks it came from George and dismisses upon learning that Dobbin provided it. Marxist and similar schools of criticism that go further and see Thackeray condemning consumerism and capitalism, however, largely overstate their case. Thackeray is pointed in his criticism of the commodification of women in the marriage market, but his variations on Ecclesiastes's "all is vanity" are more personal than institutional. He also has broad sympathy with a measure of comfort and financial and physical "snugness". At one point, the narrator even makes a "robust defense of his lunch": "It is all vanity to be sure: but who will not own to liking a little of it? I should like to know what well-constituted mind, merely because it is transitory, dislikes roast-beef?"
