I grew up comfortably in this "Intellectual Class" but Dad remembered the hard days of the Depression and his Grandfather's hardscrabble farm. The angriest I remember him getting at me was when I casually tossed out some sneering reference to the problems of the Working Man. He had no patience for that sort of thing, and so I had a correction to the Class Condescension problem at quite an early age. Fortunately, it stuck.
And so while I am a card-carrying member of the Intellectual Class (multiple papers published in the technical literature and all that), I feel this same rage at the sneers from people who should know - and behave - better. There's no mystery to me about what Trump's appeal is, and in fact there is a sense of kindred spirit: he, too, came from this same class. He, too, rejected the easy prejudices of that class. He, too, is impatient with those who should know better.
It's quite an interesting interview, and I highly recommend it.
