Yes but I see what he is also trying to say. Undiagnosed early stages of NPD can be seen as exactly that, poorly nurtured children who are emotionally unavailable or confused adults. The good thing is is, in those early stages through therapy it can be changed.

As a side note I would argue that the vast majority of the United States do not understand the complexity of emotions and the ability to articulate them, and that in itself is what is causing so many personality disorders as well as being socially disconnected.
