"Experience has shown that even under the best forms [of government], those entrusted with power have in time, and by slow operations, perverted it into tyranny; and ... the most effectual means of preventing this would be to illuminate, as far as practicable, the minds of the people at large ..."
~ Thomas Jefferson
So the next time you wonder why schools don't teach about American History or the Constitution (among other things), re-consider what Mr. Jefferson said. It's a deliberate plot, begun by the Progressives over 100 years ago, to "dumb down" the U.S. population.
The inverse of what Jefferson said is, "Ignorant people are easily enslaved."
