The top one percent own about one-third of the assets in America and 40 percent of assets around the world. This concentration of financial resources in many countries gives the ultra-rich extraordinary influence over elections, public policy, and governance. Darrell West's Billionaires analyzes the growing political activism of the ultra-rich and the manner in which they have pioneered more activist forms of politics and philanthropy. With the "wealthification" of politics and society, it is important to understand what this concentration means for system performance as well as social and economic opportunity. West takes us inside the world of the super-wealthy through insightful analysis of U.S. billionaires such as Sheldon Adelson, David and Charles Koch, George Soros, Michael Bloomberg, Bill Gates, Peter Thiel, and Tom Steyer. And looking abroad, West analyzes the billionaires who have run for office in nations such as Austria, Australia, France, Georgia, India, Italy, Russia, Thailand, and the Ukraine. From oligarchs in Russia and Eastern Europe to princelings in China, tycoons raise important questions about political influence, transparency, accountability, and government performance. This book argues that countries need policies that promote better transparency, governance, and opportunity.
