It's quite a leap to say that students don't have to worry about paying for food or rent. I would go out on a limb and say millions of students do just that.
Don't get me wrong--I'm paying for food and rent--just for many (most?) it's covered in their loans/scholarship/whatever. I guess I wasn't thinking about people who work at the same time, though. (My school requires everyone to be on a meal plan and to live on campus or prove that they can live off campus, so I forget that people at other schools have to worry about it.)
