If I shake hands with the top 10% of SAT scorers in the country, then 10 years down the road determine that their average earnings are greater than that for their age cohort, does that mean my handshake is worth $200,000? This is precisely what universities do and argue that buying into the massive education bubble is still a "good investment" since you earn more. I have no doubt there is value to classroom lecturing and the "soft" features like interaction with a wide range of your peers (assuming you choose to leave your dorm room), but the value of college can't be estimated by earnings differentials between college graduates and non-college graduates.
