IIRC, the strongest predictive factor for SAT scores is... parental income. So if what these tests are measuring is not a "general factor of intelligence" but "quality of home environment", you can readily see how that could correlate well with outcomes like "success in later life."

SAT mixes in intelligence with education so it's bound to skew more towards people with access, but it's also correlated with IQ, and IQ has significant heritability as well (things like separated twin studies have shown the genetic component quite clearly). So it's probably a double whammy there - good environment and good genetics.
