What do we teach kids

Do we teach them what is required or we teach them what is convenient to the world in a manner that the kid grows up as a conformist instead of a non-conformist? Is the primary and secondary education system which we have today allows a kid to grow and have a personality of their own. Why is it that we teach them about national heroes instead of businessmen or the administrators or for that matter the corrupt politicians? Why none of the text book any where in the world is allowed to list mistakes of current governments or some recent governments.

I believe we all are too comfortable believing the place in which we live to be perfect adobe for ourselves. We all have accepted somewhere in our sub-conscious mind that this world is not a good place and we want to project a false image to our kids.
