A few years ago the Citadel CEO went through a very public and extremely acrimonious divorce, during which the wife and kids left Chicago for the east coast and refused to come back. So now, he's all alone, and seemingly getting angrier by the day. His politics are increasingly distanced from what people in the area are interested in, etc.

Moving to a location where he might see his kids more often might just make him a lot happier and less angry. If so, that's good for him.
