The Spread of ignorance was well underway decades before immigration, legal and illegal became a real factor. There has been no history taught in the schools for fifty years, and no civics or geography, little or no English. The schools inculcate attitudes rather than educate which makes the population over a human lifetime into the mass of nonthinking interchangeable parts that make a Communist Utopia seemingly inevitable and its faux facsimile probably unaboidable.
Forgetting the leading role that faith played in forging the nation’s path is the foremost folly of all. A case could even be made for a secular study of the consequences of faith and of common failure modes of faith. It would start with theological theory common to the faith traditions of the west. The beauty of this is that it would be all witness without any official exhortation. And therefore would pass even our modern secular muster.
