Corruption costs an estimated $1.5 trillion per year worldwide, and it often takes the form of heads of state and their families looting public treasuries and expropriating resources for their personal gain. Less known is the fact that Western governments are sometimes complicit in this kleptocracy, particularly the United States, often out of America's insatiable thirst for oil. Filthy Rich is the result of a one-year investigation by CNBC Senior Correspondent Scott Cohn and the network's Investigations Inc. team. This original documentary focuses primarily on two countries: Azerbaijan in Central Asia and Equatorial Guinea in West Africa. Among the most corrupt countries in the world, the ruling families of both these oil-rich nations benefit from their close ties to the U.S. In the modern world, the U.S. is forced to make a choice between U.S. oil interests and U.S. values; Filthy Rich finds that all too often, U.S. oil interests win out.
