As a CV is a way of listing your education... (amongst other things.)

If you don't use your education then it is at best a bit self indulging. In order to use said education, it starts with a CV.

Interestingly, although in later years I wrote a PhD thesis, I never "went" to university and in all my work, both in private and public sector, have always insisted on "or equivalent experience" where traditionally degree level candidates were required. When as Chairman of a public sector body, I appointed a chief executive who had a couple of O levels to his name, although could never prove it.. He was one of the most able people I have ever come across and was a breath of fresh air in a sector known for perpetuating old ideas.

University can be either coherent (Law degrees, medical degrees) or they can be about expanding your horizons, but for an argument regarding cost to be valid, it has to be in the context of career path, or put simply and I admit flippantly, its about a CV.
