But the US labor force is increasingly composed of African Americans (average IQ of 86) and Hispanics (90) [1], versus Chinese labor force consisting of Han Chinese (average IQ 106). Thus it still has no competitive advantage.
Because I'm calling bullshit on those figures, IQ tests are notoriously unreliable across cultural and societal boundaries.
Hell even across economic boundaries within the same society.
That's irrelevant. What matters is what they _are_ reliable for.
