Unpopular take here perhaps, but I rather like the Diversitarian educational system. It re-emphisizes the sorely neglected third level of classical Liberal Arts education. In short, one starts in grammar school, learning all the baseline facts. Then one proceeds to logic school, learning systems of logic by which to process facts. Then, finally and most importantly, one goes onto rhetoric school, learning how to express those facts with eloquence and skill (usually the arts come in at this level as well). For new insights can be gained through rhetorical excellence, through an ability to cut through to the heart of the matter, and so forth.
Now, IOTL, this system has largely been dismantled in favor of our current mishmash-system of vocational training walking in the skin of a real Liberal Arts curriculum, aided along by an academia that tends to prefer vacuous jargon to any real insights. Most have the equivalent of grammar school, some have some training in logic, but rhetoric is sorely lacking, outside of some public speaking. Schools have been shuttering rhetoric departments for a long time. Perhaps a three-level system more like that would be a good fit for the Diversitarians.
