What I understood about this chapter is that language education depends directly on the education of people since they are child , is crucial to their education. So it should not be allowed in future mistakes that can damage your language because in school children are expected to be able to read write and speak properly and it is not healthy and right that for sentimental reasons, this caind of behavior be allowed.
Is also important to note that in the last chapter we found that in fact humans are programmed to speak and communicate orally, but we must also learn the leguaje correctly and that starts at home.
