Every single company in the world has a business aspect, (from the guy who mows the lawns in your neighborhood up to Microsoft and Apple)
They all need time management, insurance, finance, negotiation, sales, accounting, legal foresight, training, and tons of other stuff you learn by going to college and getting a general business degree.
I was recently on the job market (have a bachelor’s in business) and I was getting call backs and third and fourth interviews from several different companies including:
Retail store manager (even though I don’t have retail experience), and manager at a medical company (even though my previous experience is in hospitality and not medical) . . . it’s all because there really is no limit to where you can go when you get a degree like that.
And when you are in the business program, you may get inspired to focus on something specific. But if you don’t, once you graduate you will have a set of skills to take anywhere and once you get your foot in the door somewhere you can decide what skills you want to build utilizing your knowledge you learned in college.
Now is a good time to go too . . . while the economy is down you can focus on school and use student loans and grants to pay for living, and then when you graduate in a couple years we all hope there will be more jobs!
To answer your question (LOL), there really is no limit as to what you can do with a business degree.
