Average doesn’t mean that’s the amount every student gets – or even that most students get. If one student gets a full ride ($70k) and another gets $0 in aid, the average grant is $35k. The average doesn’t tell you much.
Complaining won’t help your daughter. You really need to figure out how much you can pay out-of-pocket. I don’t think any organization is going to give you $40k/year so your daughter can go to Yale. If your ceiling is $30k and your daughter is a senior, you might want to invest some time in finding schools that offer merit.
