if you want a back up plan, why not put in some hard work and get a degree with some value like accounting. accounting majors probably have some of the best career prospects right now without further education. probably start slightly lower then engineering as far as salary, but can move up quicker in some cases. if you are in school, you might as well get something of value for your money. other then core B-school courses, marketing and management majors do not gain much of substance.
