"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
-C G Jung
So I would be against those states that would get Rid of the Test. As like Liz and AG pointed out.....some people have things happen in their families wherein some may be forced to take care of their Parent or Parents, be forced to take on responsibilities of an adult.
Also I would have to Agree with RA.....on just raising Prices as in doubling like overnight. Plus I have known other adults that went back just to get a Diploma. As they always wanted to graduate. But Never had the chance due to what came up in their lives.
Another issue would be for those kids that want to join the Military but had dropped out. Without a Diploma today they can't in, as there is no draft.
