In Freudian psychology, there are 3 phases of personality development starting with the "Id" which is the child stage. The second stage is the "ego", characteristic of teenagers/young adults. The 3rd stage of development is referred to as the ______________?

Hint: Donald Trump is to the "Id/ego" stage as Bernie Sanders is to the final and more compassionate stage. And Hillary, who knows. She could be any one of the 3 at any given time. And depending on her mood, ready to push the button that could destroy the entire world at a whimsical fancy. As in, "Let's see......, what should I do today."

And because most American politicians lack this 3rd stage of development, the power of the Presidency should be reduced.
