Unlike a computer network all problems are not the same in education. You don't start out with a faulty switch and change it out. There are no magic programs. Sometime the circuits are bad and nothing can be done. A kid just can't be replaced. It's not 1's and 0's each one is an individual and often has problems at home that the teacher can't control. These are children not buggy whips or parts made on a CNC lathe. To compare a child with a product shows a vast ignorance of teaching and of human development.
If you don't understand my point, just say so. But to make silly excuses for incompetence of curricula and personnel is not helpful.
If the points you make were relevant, we'd have had these educational problems since before the founding of this nation.They are much more recent than that.
WE ALL are responsible for OUR OWN choices in life and how we live it. What we learn and how we apply it is chiefly up to US.
