We might be in the same boat with two in at the same time.
Anyway, it seems that this change will have the largest affect of families with few savings. Parents with two or more in at one time are now clearly more likely to require loans than if their financial burden was spread out.
I see how people could see the current system as unfair. But if that was actually the root of this change, the aid system could have been modified to consider the number of children from a family that had already gone to college.
