I would also argue that there are missed opportunities by leaving school early. Some of my best professional relationships started at Michigan State and they continue to help me build my career.
Also, $200K+ in student loan debt? Where the hell was he going?
EDIT: Also, why not just start the damn company while you're still in school? I'm sorry, but I had more free time in college than I can remember and having a side project was not a huge deal. No different than when people start their business on the side while still maintaining their 9-5.
EDIT 2: Full disclosure: I work for MSU as an adjunct so I have a strong financial interest in people getting their degrees (especially in STEM fields!).
