Economics Degree Review: Story of an useless degree
Some degrees are obvious in their lack of 'real world' career usefulness. A degree in virtually any form of history is only going to be useful to universities and perhaps certain types of historical preservation groups, and even then they're going to want those to be post-graduate degrees. There are more doctorates being handed out in almost everything than academia can absorb, so there's been 'credentials inflation' for everything they can be even tangentially applied to.
Economics is one of those, along with Anthropology, Sociology, and many (Most? All?) of the social sciences.
Only a precious few bachelors degrees leave you with directly applicable practical skills (medicle, architecture, etc.). Most degrees serve mostly as a signal of your ability to learn and perform tasks required by employers. (As you may have learned, economists call this the sheepskin effect.) You will learn most of your actual skills on the job, which is why experienced workers tend to earn more.
