The American educational system has been dragged through the mud for the last 40+ years over the idea that all children can be geniuses.
We have cut and cut and cut. Some kids are "gifted", and get to take Calculus; algebra is no longer standard curriculum. English grammar has been cut back. Latin and Greek are too hard for the less-special of us.
The school system is targeting "success", in that "we can all succeed", by lowering the fucking bar.
