I don't think it's that common from what I've seen in close to 3 years at a regional. A lot of people I work with made it happen themselves, and have the debt to prove it! . I paid for everything myself, and don't have loans. But it also took me longer.

Either way, it doesn't bother me. One of my good friends had a lot of help from his family, basically paying for everything. But he's a great guy, and has helped a lot of people in this industry out (including me, big time).
