At the DNC, Elizabeth Warren lashed out at Donald Trump's personal self-absorption.
Psychologists have a term for that: narcissism. And according to a number of researchers, it's an epidemic today. Younger generations, found psychologist Jean Twenge, are especially vulnerable to this preoccupation with the self. Here you can order her now-iconic book "Generation Me."
Also, the reality is that many leaders are narcissists. And that, as the Harvard Business Review documents, can be a useful trait. It might also be a necessary one to keep the trains running on time and efficiently.
And, what lawyers worth their salt don't have a strong sense of their own importance? Likely they need that mindset to operate effectively in a legal system which is primarily adversarial. (Mediation is the exception.) In court and in transactions, they have to go in there and do battle for their clients. Also, the theatre they must create is scripted with self-involvement.
Perhaps a trait looked for in applications to law school is narcissism. Without it, lawyers might not be psychologically suited to be advocates for clients.
The danger is not narcissism itself. As with most human traits, the peril emerges when the mindset becomes excessive. What results is a delusion of infallibility and that is it okay to engage in any kind of behavior. That's when organizations and nations experience tyranny.
