The fundamental problem isn't Trump, the GoP, or any other individual actor. The fundamental problem is that representative democracy, like Marxist-Leninism, is predicated on an entirely fictitious notion of human cognitive behavior. Mencken's comment about democracy being the pathetic belief that collective wisdom can emerge from individual ignorance is highly pertinent. Worse yet, what we've learned about human behavior over the last 75 years clearly shows that representative democracy is almost the worst-possible way to attempt governance. But we remain fixated on the idea that it's actually adequate and thus we're doomed to generate the inevitable tyranny that Plato pointed out is the inexorable destination of all attempts to let ordinary foolish ignorant people have any say in the serious and difficult business of government.
