How much is your local dictator worth?

"What trillion dollar bill?" From the Forbes list:

Fidel Castro
President/Cuba
$900 million
Age: 79
Comandante since 1959.

We estimate his fortune based on his economic power over a web of state-owned companies including El Palacio de Convenciones, a convention center near Havana; Cimex, retail conglomerate; and Medicuba, which sells vaccines and other pharmaceuticals produced in Cuba. Former Cuban officials living in U.S. assert that he has long skimmed profits. Castro insists his net worth is zero. (Editor's Note: Emphasis is mine.)
