I think college doesn't define your future livelihood at all!
I'm currently a college senior who attended a pretty good university (we're nationally ranked 35th in the US and 7th in my major), so trust me on this. Other than a diploma and the "recognition" that comes with attending a school with a super good reputation, you're getting jack for your degree. All the stuff they teach you in class, you can just as easily order books from Amazon and teach yourself without spending 100 grand for a 4 year tuition.
I double majored in Neuroscience and Biology...and once I graduate I'll be working for a tax referral company as a Marketing Manager.
Don't feel limited by your major. If you want to try a new field that you have no experience in, just emphasize how the technical skills that you acquired will set you apart from other candidates and actually make you more qualified in the long run.
