Because you're only applying economy of scale to a single market. What I tried to illustrate is that different classes would spend the money differently. So it isn't just everyone buying cars. Come on, that's idiotic and unreasonable. But what I'm saying is that new people are entering MANY markets. Not a single one. That there are so many markets and that we are no where near full market capture (this is the important part) that thinking just rent would go up is also an unreasonable assumption.
