The degree is definitely helpful when finding a job. It gets your foot in the door. I spent 4 years in college as well with no degree to show for it. I get paid pretty fat, but it took me 7 years to get here.
However after spending all that time in school, I can definitely say this: Don't go to school unless finishing is the most important thing to you. It wasn't for me and that's why I didn't finish. I don't regret it. Although, I do intend to go back when one day...it is important enough to me to finish.
