I got a degree in Petroleum Engineering - scheduled to finish it in 87 but the oil market crashed in 85 which had me in no hurry to finish college. Instead I joined a couple rock bands and had a great time playing around the Albuquerque bar circuit until my parents got fed up and insisted I finish any degree - marketable or not.
So I finished the PE degree and promptly spent 1.5 years doing menial jobs until I broke into a programming gig after a year taking heat for screwball hackers on a help desk.
College is only useful as an objection killer as its an arbitrary filter that gets used by HR doing a first cut on a stack of resumes. What you learn is usually not that valuable. A quick survey of adults out of college more than 5 years shows that maybe 10% are working in the field they studied in college.
