Those who come out of public schooling with an education gained that education despite the best efforts of the public school system.
I had a friend who was thinking of re-enlisting in the Air Force reserves as a flight engineer. He had been a hydraulics mechanic and the offer was that in return for a 39 week school, you incurred a six year reserve commitment. I went down to recruiter’s office with him. The recruiter told me that he had a guy who had graduated from C.W. Post College (probably “The C.W. Post University” today) who could not pass the entrance exam for Air Force enlisted man. That individual had been defrauded by the American education establishment, there is no other word for it.
