Scott says one of the pillars of modern capitalism is trying to persuade people to buy things they don't need. That is why advertisers put so much effort into trying to persuade someone with a perfectly good automobile that they need to get a new one, or a person with a perfectly good flat screen TV that they need to get a bigger one, or that the hamburger they bought isn't tasty enough and they should pay an extra dollar to get the good one. If companies ever succeeded in selling every person in the world a new blender they would immediately get to work trying to convince those people that the blender they bought isn't good enough and they need to get a new one.
