Is getting a Business Degree worth it?

I am kinda in a dilemma, which major to pick. But a bit biased, towards business sides. As well as worried about what opportunities come with this degree, in comparison with a STEM degree

Think the one question you should ask yourself is = do you plan on starting your own business or do you plan on joining a company that is based in a particular sector. I have 2 uncles. Both ended up doing business but one chose to go to college and the other didn't. I also had a cousin who studied biology and another who studied food science. Both went on to work in business. The thing is a lot of people say that you don't necessarily need a business degree to do business because any other degree could lead to you doing business. A lot of people do undergrad STEM and go to business school down the line and get an MBA (top 5 most popular degree after completing a STEM degree). I feel like a STEM degree would just give you more options. Depending on which country you are planning to study at, you could even take business classes alongside your major requirements. Hope this helps!

The main reason I am considering a Business degree is because I want to start my own business/ startup. And I am planning to move in UK (If possible then permanently). Like Undergrads in Aston Uni, and after that I want to move in to London. Is it a good decision? And How is the Aston Business School tho? Like reputation wise, coz I am taking a degree to just broaden my Network, and meet new and like minded people.
Another reason is, if my business does not work out I will apply for a viable job and have a secured income.( This is like my least preferred future)
