BTW the highest IQs are in East Asians. Our labor force quality is diluted by Affirmative Action and grade inflation.
After decades of the Welfare State and Leftist control, I doubt there is any field which is full of competent workers
In the early 1980s, the average IQ in the USA was 100, when the population was 270 million.
By 2010, the average IQ in the USA had dropped to 98, with the population having increased to 320 million.
For a population this large, that represents a plunge into the abyss. Immigration into the USA is overwhelmingly weighted toward the lower IQ masses from third-world cesspools.
