The statutory status quo in America produces an income-distribution that is heavily weighted toward the top wage-earners. Suppose I thought this was unjust, and was arguing for changes in the law that would redistribute wealth more equitably. In the course of my argument, I might mention that the "average worker" makes such-and-such per year. What sense of 'average' should I use to make my argument more convincing: mean or median? Explain.
