Not true. I took a few semesters and I was going for a major in physics and a minor in astronomy and even that isn't anywhere near a guaranteed job.
Did you look that up before you enrolled? You do understand that college's operate like a business, they won't tell you what job fields are available or anything, they'll just tell you how much it is to do what you tell them you want.
Do the research before you enroll, then you won't have that problem.
BTW, did you even finish? You only said you took a few semesters... how do you even know if you haven't finished?
