1. Teodoro Obiang Nguema Mbasogo, president of Equatorial Guinea
He's Africa's longest-serving ruler, an autocrat who leads the tiny, oil-rich West African nation of Equatorial Guinea. Despite its vast natural wealth, the majority of its people live in deep poverty with no access to clean drinking water, proper educational or health facilities. One fifth of children die before age 5. The money has gone into the pockets of Mbasogo and his family. They own luxury properties in the United States and other countries, a private jet and a fleet of luxury cars.
