Also the class got bigger and more pupils became anti establishment ilk,making it harder to teach even if you were good at the job, respect fell (the main reason) for all and governments started interfering with how you could teach leaving a whole generation not really sure of what they were supposed to be doing.

Today to be fair schooling standard is reasonably good in the main thanks to computers bringing everybody back to a same same level. Spelling is not high on the agenda unfortunately nor is reading as humanities and individual well being is more what they are trying to teach in schools so collage and university is really where education of communication is developed.
