Why is it that the anti test score argument almost always tries to chalk it up to hiring tutors? They consistently try to make it sound like people "buy" higher test scores with tutoring in order to discredit tests like the SAT
It's true that people who are otherwise well off are more likely to have test prep, and those people's test scores are often several standard deviations higher than low-income students from bad schools without test prep. But the counterfactual of (same person) +/- test prep = about 40 SAT points.
