And most schools require one from everyone. Even those who, by their own admission aren't going to qualify for need-based aid.

I've never heard of a school requiring a FAFSA. I've only heard of them requiring a FAFSA if you wanted to be considered for aid.

I filled out the FAFSA for my kids' first 3 years of college, but am not bothering to do it this year for their senior year next year. I originally filled it out knowing that we wouldn't qualify for any need-based aid, but also knowing that my job was not stable, and if my job situation changed and I had filled out a FAFSA, I could call the Financial Aid Offices and explain my change in situation to see if they could find some aid. If I hadn't bothered to fill out the FAFSA, that option would not have been open to me.

Now, my job did go away, and after a year of no income, I filled out the FAFSA, and they still didn't get any aid, so this year I'm just not bothering.
