Colleges and universities have been around since the Middle Ages. They've always had more than one purpose. First, they function as a way for young people to transition into adulthood in a quasi-sheltered environment. Second, they prepare some people to enter a profession right out of college. That was true back then just as it is now.
However, it is not necessary for your major to funnel you directly into a job in that field. One way to look at this is to understand the third purpose of higher education is to train and discipline your mind in ways you are going to need, whatever you major in and whatever you end up doing in life. Another is to view college as an opportunity to study something that interests you but that you don't plan to make a career, so that you may never be able to study it seriously again. Finally, in the US, at least, certain professions can be studied on the graduate level only, or we require advanced degrees to enter them seriously, but a number (law, medicine, etc.) don't demand any particular undergraduate major. You should therefore use your undergraduate years to study whatever you want.
I know doctors who majored in English, Political Science, or Art History while taking the pre-med classes to prepare for medical school. Those were subjects that seriously interested them, and they think they are better doctors for having chosen something other than the standard chemistry and biology majors. They are more widely educated than many of their peers.
It's narrow-minded to think that studying something that doesn't lead directly to a job is a "waste" or "stupid". It is not. My first job right out of college had nothing to do with my major, but that didn't bother me at all. I still loved my major and eventually I returned to school and earned a PhD in it. Even if I had remained in that job and made a career of that field, however, my undergraduate major would still be affording me much pleasure, as an avocation. I got a great deal out of it, and you, whether you realize it or not, have gotten a great deal out of yours. You may someday be in a better position to recognize that.
