I'm 25 with a 6-figure job, and I don't live in NY or California. I have a bachelors degree. Would I be where I am now without going to college? Unlikely.
I'd also like to mention that the education you get from college only comes half from books and classes. The other half is social skills, independence, and growing up. Just like your career, you can learn these things outside of school, but if you make it through college (not living at home) odds are you have become a well rounded, interesting, socially capable individual. So much in life hinges on these skills - friendships, relationships, interviews, family, etc.
I say this as someone who was at one time your typical shy teenage nerd who could count his friends on one hand and spent 90% of his time playing MMOs. Now, while still a nerd, probably my favorite thing to do is go out and meet new people. I'm not sure I'd have have come out of my shell had I not gone to college.
