Yeah, data can be beautiful - but is ugly if presented misleadingly. Only very little can be concluded from this 'graph' (without sources btw), but it is presented as if the inner west are the great core of enlightenment, spiraling out to the 'dumber' nations. The level of knowledge excellence is obviously related to the amount of dollu spent - which is nonsense. My equally valid opinion is that Western liberal/Capitalist education is exceedingly inefficient, and only optimized for wage-slavery. Notice how all the super 'edumecated' citizens from the west have been so easily propagandized to think that Russia is the bad guy. ..China is the bad guy ..socialism is bad ..communism evil ..Capitalism GREAT! We are the best!! ..and so on and so on with similar infantile propaganda from the Capitalist elite. The average intellects in these 'educated' western nations is Embarrassing, and misinformation from constant propaganda doesn't help much i'm afraid..

I guess when you consider that citizens of rich capitalist countries have to throw away so much of their income in commodified and privatised education, I guess that it is possible that countries like can spend near the top.
