Park Avenue: Money, Power and the American Dream is a 2012 Alex Gibney's film based on Michael Gross's book "740 Park: The Story of the World’s Richest Apartment Building" 
740 Park Ave, New York City, is home to some of the wealthiest Americans. Across the Harlem River, 10 minutes to the north, is the other Park Avenue in South Bronx, where more than half the population needs food stamps and children are 20 times more likely to be killed. In the last 30 years, inequality has rocketed in the US -- the American Dream only applies to those with money to lobby politicians for friendly bills on Capitol Hill.
