Should I change my major to likely get a better job or is no major economically beneficial right now?

You're wrong. Unless you graduated from a top program, businesses do not assume you are more qualified simply because you majored in business, and they're probably not even going to know what "marketing education" means without you explaining it to them since that's not a common degree. Once they've determined you have a BA and it's from a reputable university, all they want to know is what skills you have. And with a little strategic thinking and possibly some supplemental experience through electives, internships, volunteer work, or other opportunities, you can easily make the case that you're qualified with your existing degree, especially if you're looking at market research positions. If it turns out you need a formal qualification later, you can always go back for an MBA.
