An American prosecutor once told me this joke:

Three elite government officials become friends on the conference circuit. One is from a developed Western nation, another from a developing nation, the last from a Third World basket case. When a conference is held in the developed nation, that official hosts a dinner at his home, a fine three-story house in a prestigious neighborhood with a four-car garage and an outdoor pool.

The other two officials can't help asking how he can afford such a home on a government salary. He leads them to his study on the top floor and points to the river, asking, "Do you see that toll bridge over there?" His friends nod. "Well," he whispers, "10 percent of everything comes to me."
