So sad... The graph at right (click to embiggen; source) jibes with my own experiences hiring people here in the U.S. vs. in Estonia and Russia. I still remember my utter shock when I first evaluated potential employees in Estonia, back in '93 – their superior math and science knowledge, in particular, were simply stunning when compared with typical American candidates.
A few years ago, I sent the video at left to a friend of mine in Estonia. His response? He was positive it was a put-on, that those couldn't be real people randomly interviewed on the street. No adult, he said, could really be that ignorant.
