The US is at the point where 30-40% of the country would drink bleach and shoot their neighbor at the presidents command while probably similar numbers are functionally illiterate. Not to say the democracy has been functioning, but you can't have a functional one with these preconditions.
And its structurally intentional. This is all a product of decades of machination and effort to craft this cultural zeitgeist of zealotry and active war against one another while robber barons pillage the commons.
