Dr. Heyman realizes that doctors use jargon to speak with other doctors. When they use jargon to speak with patients, there is a lot of misunderstanding. The same is true for economists who communicate with words that sound like double-speak or gibberish to the uninitiated. The author uses cartoons, where an economist would use a graph. He uses basic vocabulary, and shuns esoteric terms. There are no long lists to memorize. The plot goes behind-the-scenes to show what a family ready to buy a new car feels and experiences.
