Monaco may be the second smallest country in the world, but it is also one of the richest. Almost a third of its residents are millionaires, lured to the French Riviera city state by its lenient fiscal policy -- income tax was abolished in 1869. It is estimated that 70% of the population is foreign-born, while just 10,000 are locals, "the Monegasques."
