Park Avenue: Money, Power, and the American Dream, a documentary on PBS exploring the gap between the rich and the poor in the US. It focuses on some of the richest most powerful people (such as David Koch), who live in 740 Park Avenue, and highlights their political connections and political power. It also addresses the populist movement which is hostile to taxation of the wealthy, even though so painfully few benefit from the tax breaks and at such cost to so many.
It is informative and straightforward. I would have liked some more analysis of cultural issues that might provide some insights into why people in the US are not outraged by extreme income inequality and the excessive wealth of so few people.
