What do Mick and Bianca Jagger represent?

Bianca and Mick Jagger represent the new ruling class of New York’s social elite. The Jaggers were considered to be the "it" couple of the late 60s and 70s in New York. When the paparazzi abandoned the Swans to chase the Jaggers down a New York street for a photo, it demonstrates the end of an era for Babe's social set. Soon, this ruling class would disappear into obscurity and the masses would, instead, worship rock stars, fashion models, and other celebrities of the moment. Breeding and inheritance no longer had the same status and the Swans would soon become extinct.
