In part this initiative rewards bad parenting and lack of responsibility for raising your kids.
If you made imense effort to provide the best education possible to your child, to put him in a good school (even if that meant depriving yourself from a better material life and having 2 jobs), if you kept a non perfect marriage because that would be better for your child, if you only had one kid because you couldn't afford to provide a good education for more than one, what this law is telling you is: bad luck, you shouldn't have done it because now, we are going to adjust his score back for it so that none of that matters.
