The first difference is in the area of *directness*. A working-class audience likes to know exactly what you are trying to do or say to it. A middle-class audience prefers obliqueness and innuendo. It likes to feel the superiority of exercising its perceptions which may have been so expensively acquired, thus opening up areas of ambiguity and avoiding any stark choice of attitude.
