They don't,Guest, because a poorly educated population is easier to control and dominate. And...they'd rather not spend the money to do it.

As for that, why do you think so many Americans turn out to be shockingly ignorant about the world outside the USA or even about their own geography when questioned about it by press people who do surveys on such things? For the same basic reason...they don't receive a very good education in their schools. It's too onesided and USAculture-centric. It leaves out a lot of info that might open their minds. It encourages them to become mindless consuming units...little unthinking cogs in a big buy and sell machine.

Nothings aids any totalitarian system like feeding its people a steady diet of carefully controlled, edited, and slanted information, you know...and just leaving out the parts that might get them thinking differently.
