People like Us: Social Class in America 
120 min. 
From threadbare Oriental carpets and lawn ornaments to balsamic vinegar and, 
oh yes, money, “there are all kinds of measures of social class in 
America,” 
notes society columnist R. Couri Hay. Filmmakers Louis Alvarez and Andrew 
Kolker, whose wry 1997 survey of public life, Vote for Me: Politics in 
America, won Emmy, DuPont and Peabody Awards, explore how class can color 
everything from food to high school. They also visit people who are 
representative of various classes and events celebrating them, like the 
Baltimore festival honoring waitresses who call everyone "hon." The 
filmmakers also interview various social observers, including author Joe 
Queenan and columnist Stanley Crouch.
