Here is an interesting article about the relationship between student's SAT scores and parents income. The higher the parent's income, the higher the student's score. This is an example of correlation not being causation. In our society, on average, the higher one's IQ, the higher one's income. And, on average, the higher one's IQ, the higher one's children's IQ. Progressives don't like to acknowledge that there is such a thing as IQ, except when bragging about their own. Obama and other Preogressives would very much like to alter the situation where one's IQ correlates with income. That would have negative income on the nation, but Obama and other Progressives are intent on equal distribution of wealth, and are not at all concerned about reduction of the ability to create wealth.
