Part of the answer is paying attention to events, looking for the illustration, looking for the dramatic motivating example. It kind of helps to use various people as foils. If someone has said something that's demonstrably at odds with experience or just demonstrably stupid, I use it. Jean-Claude Trichet [former president of the European Central Bank] delivered some wonderful quotes. Olli Rehn [vice president of the European Commission] has been doing beautifully helpful quotations. I'm not being unfair to him. The austerity thing has been helped on a great deal as an argument by unfolding events in Europe. In 2010 it was based mostly on the logic of the case, not the evidence. Now I can say, "Look, you've done this thing. Look what's happened. Look at Britain. Look at Portugal."
