Democracy will never work because it can only work if EVERYONE is educated enough and by default humans are notoriously stupid and unaware of their own stupidity.

In this case, I would not call it stupidity - I would call it inherent, (very human) instinctual biases and tendencies in dealing with contradictory thoughts in your mind.

Or what most of us understand as cognitive dissonance.

I would imagine this tendency probably arose from as a result of natural selection ranking flight or fight instincts very highly. Those who were not able to ignore or rationalize away what made them feel uncomfortable [which cognitive dissonance invokes in us] probably ended up dead very quickly out on the savanna while hunting or gathering.

However, on a personal note, I am actually very optimistic as more and more people become aware of our inherent human limitations, we can grow and become better individuals and create better social constructs to overcome our group tendencies.

Unfortunately, it would probably take a long time. Probably not in our generation.
