From a Salon interview with Nell Irvin Painter, author of The History of White People:
One of the biggest whiteness-themed pop culture sensations of the past few years was the blog Stuff White People Like. Many people thought it was racist. What did you think?
I was a professor at Princeton for a long time -- and I did my Ph.D. at Harvard -- and I circulated among wealthy people. So much of what is considered "what white people like" is what middle-class people like. I live in New Jersey and we have middle-class people of every background and we all like those same things. It's very common, particularly in the 20th century, to make the equation that white means middle-class. It's a lazy equation, and as time goes by it becomes lazier and lazier.
