GCC Ever Complex Comparison Matrix

With so many Ranking pouring here and there it gets complex to compare and decide, be it any country but specially the GCC creed. Here is a comparison of four of the recent ones that I saw:

Interesting isn't it. Although some of the ratings dazzle me too. Like the Global competitiveness Report. It ranked four GCC countries in top 50 but also had insightful analysis like this line, "However, in many of the resource-rich countries, the availability of public finance appears - at least for now - not to have translated into improvements in human capital, which would play an important role in helping these economies that are highly dependent on oil and vulnerable to external shocks to diversify their economic base."

Well maybe cause most of the 'human capital' is a precious import instead of being an in-house production.
