Foodism has taken on the sociological characteristics of what used to be known — in the days of the rising postwar middle class, when Mortimer Adler was peddling the Great Books and Leonard Bernstein was on television — as culture. It is costly. It requires knowledge and connoisseurship, which are themselves costly to develop. It is a badge of membership in the higher classes, an ideal example of what Thorstein Veblen, the great social critic of the Gilded Age, called conspicuous consumption. It is a vehicle of status aspiration and competition, an ever-present occasion for snobbery, one-upmanship and social aggression.
