Pablo Escobar
Pablo Escobar controlled the majority of the cocaine in Colombia and built his wealth by flooding the U.S. market with the drug. Forbes named Escobar one of the richest men in the world seven years in a row. By 1987, Escobar controlled an estimated 40 percent of the Medellin drug cartel’s business. In 1989, based on public records, Forbes valued his net worth at $3 billion. Clearly this was a very conservative estimate, considering he offered to pay off the national debt of Colombia, which stood at $10 billion at the time. According to CelebrityNetWorth, his net worth was $30 billion, all profits from his cocaine business.
