The correlation between parental income and SAT score is much more formidable than that between IQ test score and SAT score.

It's actually not. The correlation between SAT score and the Armed Services Vocational Aptitude Battery is 0.86. The correlation between SAT score and Raven's Advanced Progressive Matrices is 0.72. The correlation between SAT score and Mill Hill Vocabulary Scales is 0.68 for combined SAT score, 0.71 for Verbal SAT score.

In the link you posted, the correlation between parental income and SAT score is projected between 0.25 and 0.40.
