Do the things you buy reveal your social class?

Joe Queenan gives us a tour of some upscale shops where people can buy wine with names no one can understand and kitchen utensils that your garden variety Target shopper could not recognize. He explains that buying items like this allows one to demonstrate that they are "one step ahead of the curve, one step ahead of the great unwashed" and seems to be an important middle-class trait, and part of a lifelong desire to try to fit in and impress our friends. Queenan describes this as a sort of a high school that never ends. Do you feel that in high school one of the ways that you try to fit in and impress your friends is by owning certain items? Are there items that you or your family own that represent your social class? Do you think that class is represented by the things we own? If you had to bring in one item to 'show and tell' about your social class, what would it be and why?Heres a catalog page from this winters Nordstrom Catalog. Is "Juicy" still "in"?
