The correlation between parental income and child IQ is positive. It is not 1.00, but it not 0.00 either. If the correlation is 0.4 (to make up a number), you can expect in a country of more than 300 million people to find millions of children with above-average IQs from below-average-income households. But it's also true that the average IQ of children from households earning more than $100K exceeds that of children from households earning less than $100K.
