How cool are you? One of the most important factors in a country's economic development is how cool it is perceived in the eyes of the world's young professionals. In this sense, the image is decisive. Immigrants are the most active part of the population: they move up the career ladder faster, launch companies more often, and take more risks. Apple, Google, Amazon, Facebook, IBM, NVidia, PayPal, Tesla, SpaceX, and the other companies on the chart were founded by first- or second-generation immigrants. A country can be as good as it wants, but if it doesn't have the image of a cool place, it loses a lot in the future.
