Eric Hoffer, in his article “The Cauldron of Youth” (Published on Feb 11, 1968), writes:
The ignorant are a reservoir of daring. It almost seems that those who have yet to discover the known are particularly equipped for dealing with the unknown. The unlearned have often rushed in where the learned feared to tread, and it is the credulous who are tempted to attempt the impossible. Where you see a revolution taking place without revolutionaries there the vulgar and the ignorant are at work. They know not whither they are going, and give chance a chance.
Often in the past the wise were unaware of the great mutations which were unfolding before their eyes. How many of the learned knew in the early decades of the 19th century that they had an industrial revolution on their hands? The discovery of America hardly touched the learned, but it influenced the minds of the common folk.
I think Hoffer is spot-on. A country of ignorant and hardworking folks is more likely to succeed than a country dominated by intellectuals.
