Actually, WFB winds up doing most of the interrogating, since the students, polite and attractive, seem reluctant to take the initiative. One of them, Aaron Pierce, explains the current low level of political activity on the nation's campuses: "Politics is not necessarily seen as something that's going to benefit one as a student; whether you get an A in your calculus class is. So there just isn't the incentive to go out and learn about some of those issues." If he and his colleagues were paying attention, they received from their host a capsule definition of a bedrock principle of political ethics: "I, and most conservatives, believe in the so-called doctrine of subsidiarity. It says anything that can be accomplished in the private sector should be undertaken by the private sector. If you go to the public sector, it should always begin with the lowest feasible political unit, rising to the highest--in this case, the Federal Government--only when the subsidiary units can't."
