The conversation of most middle-class Americans, we are told, revolves around consumption: what to buy, what was just bought, where to eat, the price of the neighbor's house, what's on sale this week, our clothes or someone else's, the best car on the market this year, where to spend a vacation. Apparently we can't stop eating, shopping, or consuming. Success is measured not in terms of love, wisdom, and maturity but by the size of one's pile of possessions.
