From Steven Hayward of the Weekly Standard:
Jefferson expressed more confidence that political virtue and capacity for government were not the special province of a recognized aristocratic class, but that aristoi (natural aristocrats) could be found among citizens of all kinds: "It would have been inconsistent in creation to have formed man for the social state, and not to have provided virtue and wisdom enough to manage the concerns of the society." Jefferson, moreover, trusted ordinary citizens to recognize political virtue in their fellow citizens: "Leave to the citizens the free election and separation of the aristoi from the pseudo-aristoi, of the wheat from the chaff. In general they will elect the really good and wise."
Today's establishment doubts this. The establishment is affronted by the idea that an ordinary hockey mom--a mere citizen--might be just as capable of running the country as a long-time member of the Council on Foreign Relations. This closed-shop attitude is exactly what both Jefferson and Adams set themselves against; they wanted a republic where talent and public spirit would find easy access to the establishment.
