Working at a thrift store full time making minimum wage and going to engineering school full time for the first two years, then doing tech support full time and going to engineering school full time for the last two years was no joke, and I still have debt remaining, two years out of school with a good job.
Why should it be the parents' income that anyone cares about?
Students are expected to contribute? Don't make me laugh. It's their education, they are of majority age, they likely will be paying for it and then some. How are PARENTS expected to contribute at all? Mine honestly did not and do not make enough money to have any left over after taking care of my two younger siblings (ten years younger), and yet on the FAFSA right there, an "expected family contribution".
Edit: they do, of course, make enough money combined that the government expects that they'd want to send their kid to college and could theoretically contribute something to it. They did what they could, but that wasn't what fulfilled expectations laid down by the Powers That Be.
