Re:What’s Behind the Ballooning Upper Middle Class? Education by Houshalter on Sunday July 17, 2016 @02:48PM (#12111234)
Here is a good essay which discusses why social class is a distinct concept to economic class: http://slatestarcodex.com/2016/01/30/staying-classy/

I think it's a very useful distinction. I've seen similar things in demographic statistics. Where e.g. parents education was more predictive of their child's outcome than their income. Career choice and success is somewhat noisy and random.

The underlying article by Siderea is absolutely fantastic as well. Must-read before any discussions of class!
