Good point, it's an oil kingdom that first got rich on dollars during the Arab Oil Embargo of the 1970's.
And it's been dollars even since, only more of them.
If you threw out the Qatari decision-makers though, it wouldn't have much positive impact compared to getting rid of the real stinkers around the world that are only getting worse.
Yes, Qatar is a well run kingdom. Sure, there is the issue of foreign labour malpractices, but in my experience in the gulf states they are evolving in that regard.
