In the 1970s it was unusual to see wealthy families on television. The Jeffersons with their deluxe apartment in the sky, the occasional rich couple flitting over to “Fantasy Island” or booking a cruise on “The Love Boat”—these were the exceptions. But as the economy accelerated, mass culture was suddenly inundated with images of affluence. The wave hit around 1981, as the economy slowly recovered from the stagnant wages and inflation of the 1970s. Rabbit Angstrom, John Updike’s scampering everyman, began to make serious money on his appreciating property and selling Toyotas on his father-in-law’s lot in Rabbit is Rich; Joan Collins joined the cast of “Dynasty” as the splendid and venomous Alexis; and the second edition of The Official Preppy Handbook came out, gently mocking but also instructing a peculiar subculture of well-coiffed, pastel-hue wearing teenagers who wanted to look as if they summered on Cape Cod and worked on Wall Street.
