You hadn't mentioned that your focus was on the USA, but rather a general "The targets of the theory are essentially people with non-stem post-secondary degrees" which is why I provided a paper that directly contradicts your statement. Elite Overproduction is not a US-specific topic, and the paper being from 2007 does nothing to invalidate its findings or lessen its relevance to Elite Overproduction. Funnily enough, I hadn't checked astrange's reference that prompted this discussion, which is Gambetta and Hertog.
