Two-thirds of the 'planet GDP' is covered by ten economies; over 50 per cent, by the top four of them (USA, China, Japan, and Germany) representing 28.4 per cent of the world's population. From these data, it emerges that the GDP is an exclusive club that lays down rules and practices to preside over the world economy.
Entirely different from the 'Planet GDP' is the image of the 'Planet Happiness' that appears when observing the data of the World Happiness Report, which covers 156 countries. The 'top ten happy' have just over a third of the American population. The top four are Scandinavian countries.
