Well there's two problems with that. You don't allow for the possibility that believing that "media and schools are brainwashing people' is evidence of...........brainwashing.

Now of course both 'the media' and 'schools' can be wrong and can mislead, but that's well short of designed to brainwash and well short of all schools and all media.

And really, how do schools and colleges brainwash anyone by teaching them to read, write, compute and think at increasingly higher degrees of difficulty? I call that learning.
