I am now, have been and will be wrong

Take an entrepreneur and an investors, put them in a room, and there is 0% chance that they'll be "average joes". The personalities required to go out an start a company, or fund a company are not the typical american citizen. Therefore, anyone in the room who believes that the rest of the populace is "just like them" is nuts. Egos, intelligence, beliefs are all involved in a whirling dance.
Recognize that this is part of what created and drives these people. You'll be working with/for them, and it's part of what makes them tick. How this helps you, I have no idea. But remember, handle them with care, and they won't bite.
