You’re how old? 17? 18? I’m pretty sure whoever ask questions like “why should I go to college” are young people.
So answer this question first, can you categorically say that you are 100% sure what you want your future career to be for the next 40 odd years and that at no point in the future you will change your mind? It’s a lot easier to get a college education now (funded by your parents) before “life” starts, along with bills, responsibilities, family commitments, etc. You don’t want to make an offhand decision about something that could potentially affect the rest of your life.
