Much of the world and even individual economies are becoming "winner take all" due to variations on the network effect: everyone goes there because everyone else goes there. China became the world's factory by having lots of manufacturing expertise in one spot such that few others could compete. The US lacks certain kinds of tooling, parts, and factory expertise, jacking up costs above China's. (The Chinese gov't initially subsidized their factories.) The "winners" are convinced they are geniuses, when in fact they were just slightly ahead of the pack or slightly luckier and surfed on the network effect snowball.
