Ruby Payne and the hidden rules of class

This is a bit abstract, but I'm tossing it out because some might find it of interest. My mother is an educator and works a lot with children of poverty and Waldorf education. She often throws up extremely interesting information that she runs into. Here is an article by Ruby Payne on hidden class rules. I like how Ruby Payne thinks. She's a solution-focused, very observant person with a lot of experience who is not limited or filtered in how she views things. And her observations about the differences in class are fascinating. Frankly, I'd love to see someone extrapolate them into the hidden rules of the upper middle and upper classes, if only for amusement's sake.
