The notion that through hard work and diligence, people can better their stations in life is at the bedrock of the American dream. But there's a growing sense that inequality is a persistent feature of this country. This week on EconoFact Chats, Michael Klein, and Harvard professor Karen Dynan discuss wealth inequality, and the policies that can help address it. They also discuss the future of social security. Karen has served as Assistant Secretary for Economic Policy and Chief Economist at the US Department of the Treasury.
