He goes there tuition free, his room and board are free, and he gets subsidized work during the summer. It was two weeks between when the semester ended and he started receiving his summer work paychecks - he really couldn't have saved up enough cash to cover two weeks over the course of a year?
On top of all that, he frankly has no right to be at Stanford with a 1300 on his SAT. I had a friend who was rejected from Stanford even though he was class valedictorian (at a ludicrously competitive school), captain of several school teams, and had a 1590 SAT.
He might be a bit bright, but Stanford has already bent over backwards to accommodate him. It's his fault if he isn't willing to do a little work himself. How hard is it to do 10 hours/week of research (paying $15/hr) during the school year? I (and most other people I know) often do so. He'd have several thousand dollars saved up without too much trouble (since Stanford is already paying all his expenses).
