So let me get this straight, the reason America turned into such a superpower is due to its founding stock being high class anglo-saxons with higher IQs who all reproduced together and created a kind of ubermensch class that out-competed the rest of the world, but the average white IQ in america is still 100? Is this because they count retard "whites" like irish and slavs in the white IQ average or... can someone explain this discrepancy?
