As an individual that attended an ivy league school, this article seems absolute nonsense as to the causality of the authors inability to bridge the class barrier. My "elite education" is not the sum total of my life experience. My encounters with other people, be it other ivy league educated or high school drop out, is a learning experience and always has been. Judging them from a class perspective is simply unwise. Judge them by what they say and their actions. Are they true to their word? Are they willing to negotiate or state succinctly what their position is? These are what human interactions are about. The elite attitude that is attributed to "elite education" more likely a lack of interaction with "lower class" individuals from early in childhood.
This is a good critique and I think the class focus of this article is its big weakness, but nevertheless I think the are many valuable observations that make it a worthwhile read.
