Possible Topic for Discussion: Rhetoric in Basic Education

Why does education today neglect rhetoric? Or why is it not overtly a part of basic education requirements? Most students have heard of or even played around with ethos, pathos, and logos, but why is it amiss in education? Is it perhaps because the concepts are too challenging to teach to students lower than the university level? We use rhetoric everyday, whether appropriately or not and shouldn't all students be responsible for some basic level of understanding even in order to communicate and argue effectively in their own lives?
