The top-notch dozen countries, from Sweden to United States, are technological and intellectual superpowers. Regardless of Swedish and Danish tax burden, regardless of the fact that Americans stumble in world geography, all the top twelve nations in the ranking actually own the world – or most of it.
The other dozen, ranging from Singapore to Italy, is rich, too. Countries such as France, Belgium, UK or Canada are by no means destitute nor struggling. They own a great deal of financial capital and a number of valuable brands. Sorry, though. They're not the Premier League.
Then there's the rest of the world, which doesn't own much intellectual property. These economies are mostly focused on low-tech manufacturing and assemblage rather than their own research & development. China is the leader, to be sure. Then there are “European Chinas," such as Poland, Hungary, Czech Republic, Portugal, Latvia. These countries are manufacturing bases for Volkswagen and IKEA, but the real intellectual property is owned by Germans and Swedes, respectively. "European Chinas" will hardly ever get really rich this way. Most of them are even foolish enough to subsidise foreign investors (but it's their own fault.)
It's intellectual property what matters most in the modern economy, patents first of all. Brands come as the second most important factor. Financial capital is less important, and cheap labour is the competitive advantage of the have-nots.
