The problem with this analysis is that most of this financial aid is based off of FAFSA. If you happen to fall into a common circumstance, it probably works for you, but there are many exceptions where FAFSA doesn't work out.
How does one define "rich." Sure, if your parents own a jet airplane, you are probably rich, but there is much room between having a banker father and a janitor father.
In my opinion, FAFSA doesn't adequately take into account household debt or siblings' tuition costs.
