"Sears was so powerful and so successful at one time that they could build the tallest building in the world that they did not need," says James Schrager, a professor of entrepreneurship and strategy at the University of Chicago's Booth School of Business. "The Sears Tower stands as a monument to how quickly fortunes can change in retailing, and as a very graphic example of what can go wrong if you don't 'watch the store' every minute of every day."
