I agree with ohthatssokewl that it's about emotional bankruptcy in a materially wealthy family. One additional thing that seems to support this is the sound throughout the beginning of the song that is like coins repeatedly dropping. So the first part of the song portrays physical wealth in both the mention of food and the sound of money, which create an even larger contrast to the second part of the song, when the true emotional emptiness of the family is revealed.
