 My fear, and I think it's a realistic fear, is that if that kind of concentration of wealth continues, then we get to be more and more an oligarchical country, a country that's run from the top. The inherited wealth plays a much bigger role than earned wealth and meritocratic wealth. And so you get not only real danger to a democratic institution concentrated, and that's a regression to a world that be all thought of in the American Constitution. What you want to do is make it possible for everybody to share basic wealth. So it is mobility that matters.
