I was watching TV once with a young woman in her 20's. The show, on the History Channel, I think, mentioned the war in the Pacific in WWII. The girl asked me who won the war in the Pacific.
How does an American reach voting age still so ignorant of American history as not to know who won WWII?
Here are other examples of American ignorance of history.
When the state runs schools, its primary goal is not education but indoctrination. The communists wanted to create citizens loyal to communism. The Nazis wanted to create little Nazis. In America, the New Leftist welfare state wants to create New Leftist welfare statists.
Knowledge of American history does not advance the New Left's goal. In fact, knowledge of America's individualist heritage and history of freedom can only get in the way of their goal of creating little statists.
Moreover, a citizenry that is educated at all, not just in history, is not in the interest of the teachers unions and government run schools. Intelligent, independent thinkers might question the premise of socialized education. Why would teachers whose jobs and pensions are dependent on the perpetuation of the current system want to create independent thinkers who might take it all away from them? Better to create Americans who can be lied to and controlled. An ignorant populace is an obedient populace. Obedience is the ultimate goal of state indoctrination.
Americans will continue to be dumbed down as long as that is in the interest of those in charge of young minds.
