But this doesn't adjust for intelligence. If employers are just using the degree as a proxy for a base level of intelligence (and they really are, also class) then you would see tremendous value by this measure. But really that would be 100% waste, because you could do the same thing in an hour with an IQ test that is currently being done with 4 years of college. The tech industry basically does this now with algorithm problems. Google DGAF if you have a degree if you can memorize a bunch of algorithms.
