Countries are richer when its population inherits more technology from their ancestors, except when bad governments are in charge. That is kind of obvious, really. If I was asked the question "Why are some countries richer than others in 2010?" yesterday I'd have provided the same explanation - It's because they were richer before that. What the article is saying can be reduced further: Descendants of civilizations that have moved ahead of others will stay ahead unless they stop moving. And further still: When you move ahead of someone in a race, you'll stay ahead until you slow down. That might be nice to point out, but his mission at World Bank was how to bring the less technologically advanced countries forward, not explaining why countries who used to be technologically advanced happens to be richer today. Obvious point, well argued. He says interesting things about people carrying technology around. I wonder what you can do with immigration to make your country become more technologically advanced.
