How is the system not fair to you? If your kid doesn’t get into Yale or you don’t want to pay $70k/year, you have other options. Our income is roughly 25% of yours, but nobody’s falling all over themselves to toss money our way either. We’re hovering dangerously close to the upper limit for both federal and state need based grants. Several colleges my son applied to offered him grants of $20k/year, but that only brought the net cost down to ~$25k. That’s roughly 1/3 of our yearly income. We just don’t have that kind of money (x 2 kids), so our son commutes.
Most students from low income families don’t get into the schools that give great need based aid. They start at cc or or attend a commuter school. You have the opportunity to pay for a wide range of schools. If you don’t want to pay $70k/year or you don’t like the policies of the colleges that charge that, find schools in a price range you will pay. I’m sure you’ll have plenty of great options.
