For what it's worth, I (mostly) disagree with your detractors in the other comments and agree with your sentiment (I think).

Markets care about "aggregate demand". Rich people can be lucrative individual customers because they have more to spend and often less price sensitivity. But they have limited capacity for consumption in many areas; they only eat three meals a day and only fill so many airline seats at once. The middle class and even lower classes have much higher capacity for consumption and are worth targeting - think McDonald's or even Google (advertisers want all the eyeballs they can get, even if they prefer wealthy ones)
