" A majority of both Americans and English people describe themselves as middle-class. However, as we have seen, just because they use the same words doesn’t mean that Americans and the English are thinking the same way. In America, the middle class is more an economic category than a state of mind, and membership in it is not predicated on as many complicated and specific class markers. Where Americans shop, what they buy, and how they entertain themselves are only mild predictors of whether they will identify as middle-class. The same is not true in England, where membership in the middle class is more dependent upon being the product of specific types of families and schools, and the shared tastes that one develops as a result.
