knowledge is knowledge, no matter where you obtained it. However, the connections you make during college is sometimes quite important, as they are the windows of opportunity that aren't available to the non-connected. E.g., if you have a friend in the same class, then they are more likely to refer you to their company if you are in need of a job (later in life). Or if they are already rich and are investors, you are more likely to be considered to be confounders or business partners.
If you want to run an already very large business your best bet is to go in to management consulting. In that case what you study is less important than getting top grades at a top school and interviewing like a champ.
If you want to run a business that isn't but has the potential to maybe be very large then easiest way to do that is to build your own and CS has a very low bar for entrepreneurial activity.
If you just want to run any business then no degree necessary. Just work in food service and treat it like a career. Maybe do a bookkeeping course. You'll get to manage a restaurant eventually.
