In this first installment of the 'personal interest' series, we ask the hard question of whether people, as economists would have us believe, are all looking out mainly just for their own personal interest. The example is thrown out of Lei Feng, a cultural hero known for selflessness in the service of his country. But which side is the speaker really taking on this? Can you tell by his tone?
