Here is a question about this article: The activities that constitute illegal corruption differ depending on the country or jurisdiction.

Worldwide, bribery alone is estimated to involve over 1 trillion US dollars annually. A state of unrestrained political corruption is known as a kleptocracy, literally meaning "rule by thieves".
