I don't know what to say about the Harvard quote, but with the recent admissions scandal implicating that rich people are buying their way into premium universities and into higher SAT scores, there's some nugget of truth to criticizing the current situation.
I wonder if universities aren't suffering Goodheart's Law: "Once a measure becomes a target, it ceases to be a useful measure." That is to say, once we measured that a university degree lead to higher incomes, better life outcomes, etc. and then we started pressuring everyone to get a four year degree...did it cease to be a good measure for quality employees, creative thinking, problem solving skills, etc?
I think there's something to that. When everyone is obsessed with getting the degree, and they're not worried about the practical application of their knowledge, they are doing the world a disservice. And we're all suffering for it, through higher debt and inflated expectations.
