Quote from : Understanding Power: The Indispensable Chomsky Book

Look, part of the whole technique of disempowering people is to make sure that the real agents of change fall out of history, and are never recognized in the culture for what they are. So it's necessary to distort history and make it look as if Great Men did everything - that's part of how you teach people they can't do anything, they're helpless, they just have to wait for some Great Man to come along and do it for them.
