Economics

What is the Gini index? Yesterday I saw a young couple arriving in a restaurant to have lunch, driving a car obviously bought only for sunny weekends. They gave the keys to the valet parking driver who would have to handout his monthly income to have one meal at the same restaurant, or work more than 312 years to gather the money equal to the price of the car. This is a Gini index of 56,7 the 10th highest in the world, and shows that something is completely wrong.
