I am really looking forward to hearing his answer. Jeff might have a different answer. Perhaps he is going to say that the right answer is journalists, teachers, or something like that... Or perhaps Jeff says that he does not know what the right answer is -- or that it depends on the country and culture. Or perhaps Jeff says that "the answer is the Keynesian economists" and angrily adds that "It should be crystal clear for everyone, and only people with low double digit IQs do not get it." There are many ways of looking at this question. Let's see what he says.
