The trouble is it doesn't compare like with like. College graduates are people with greater than average IQ and other skills. In the past (just 20 years ago) when less people went to college they were even more likely to have greater skills than the average person. Are there any studies that show the college "premium" for more closely matched people? Perhaps based on SAT scores. So we could see the premium for a person with 1000, 1500, 2000 SAT score of going to college vs not.
