To reside or exist in a place or among a social circle that is characterized by effete academic intelligence and thus is out of touch with or aloof from the realities of life. I don't put much weight in the advice of a bunch of economists living in their ivory towers who've never worked a real job in their lives. It seemed easy to solve all the world's problems when I was living in an ivory tower. Now that I'm out of college, I realize things are so much more complex than I'd imagined.
