Ultimately, since you're paying then you can make the call regardless of the pressure your family is exerting. If you don't think having your degree as a backstop or hedge is worthy of your time, then put it off for a while. You can go back to school should you decide differently later on.
College is what you make of it. I thought the same thing while going at it but then my upper level classes kicked in, I made better use of my time and explored different areas that I otherwise wouldn't have had exposure to. Let me also add my two cents. I was a business major w/ a focus in accounting and finance. There were a lot of courses that I took that I had/have no use for in my career. However, there are plenty that did. I'm able to help my wife structure her business and the related tax consequences ahead of a lawyer which helps keep her overhead lower. I'm able to use what I learned in accounting to not only help her, but my own clients at the firm I'm at.
You become a well rounded person which is a direct benefit if you go into business for yourself or someone else eventually. School isn't for everyone, but this is a decision you have to make for yourself.
Regardless of what you want to do, understand the risks/consequences. Everyone thinks their business with their friends is going to be nothing but success and good times...but that's often not the case.
