I'm saying that secondrary school is NOT more important that primary.
Primary, infant and junior schools are the foundation of our knowledge and vital skills that humans need for communication and improvements. Without these fully in place, we would not as a society, have all the adequate preparation for life. Secondrary school is the building up of these skills already acquired and takes learning to a further stage. Without the education beforehand, we would not be able to continue.
I agree that Secondary school prepares us for college, university and the real world. But what prepares us for secondrary school? Primary and before - the building bricks scenario, otherwise we wouldn't be ready. Without the basics, how can a society progress?
Society could progress without basics, if the basic standards were increased. If we started to teach 3rd graders algebra, then eventually that generation would be able to learn more then the one before it and so on. Yes, I agree that it would be hard to learn algebra without knowing how to add and subtract, but eventually it would come naturally to everyone and then we would all be smarter.
