You're surrounded by the children of the elite, who model the etiquette and behavior of their parents. After a few years, you tend to imitate them and that allows you to move in those circles effortlessly. That gives you access into high powered careers like high finance, strategy consulting, and corporate law where upper-middle class behaviors are required. McKinsey just isn't going to take someone with the behaviors of a yokel and put him in front of a F500 CEO even if he's a literal genius. You have to look and act the part. That's the true value of an elite education: a rubber stamp and an understanding of the behaviors and habits of the elite.
