I am in the IT field and have been for over 3 years with the same company. I am still in school along with this job and I have no degrees to offer right now and I make those #'s. I'm 21 and it is definitely possible as long as you are with the right company and you have the right credentials. A degree won't take you as far as knowing the right people
Depends on where you live, and what company it is too.
