Take a look at the chart in this post. The title of the post is “CHART: The More Natural Resources Your Country Has, The Less Educated Your People Will Be” which, while nicely politically correct does not correctly characterize the chart.
The chart does not graph the volume of natural resources the counties have but, rather, what proportion of the country’s GDP that comprises. If it did not countries like Norway and Canada would make the title look absurd as, indeed, it is. What the chart illustrates is the likelihood that a country will rely on natural resources for its GDP.
Moreover, the greater a country’s capacity for producing things other than natural resources, i.e. value-added, which would appear to be related to education, the lower the proportion of GDP that natural resources per se will comprise. In other words the implied causality is backwards.
