Prof. Karlson quotes from a Chronicle debate over the question, Are Too Many Students Going to College?, specifically the reaction of W. Norton Grubb of Berkeley:

We do have a moral obligation, emerging from several centuries of concern with equity in a highly inequitable country, to make access to and completion of college more equitable. But rather than proclaiming College for All, we should be stressing High School Completion for All, emphasizing that such completion requires either college readiness or readiness for sustained employment—or for the combination of the two that has become so common.

The whole debate would be valued reading for our political masters, who seem to have a different idea.
