What was it Kingsley Amis said? “More means worse”?

Murray writes: “Government policy contributes to the problem by making college scholarships and loans too easy to get, but its role is ancillary. The demand for college is market-driven, because a college degree does, in fact, open up access to jobs that are closed to people without one. The fault lies in the false premium that our culture has put on a college degree.”

What about Griggs v. Duke Power? Have we increased the college premium by prohibiting the use of written IQ tests by employers?
