"And the media could feasibly rectify it overnight."
But they won't!

You'll have to have a new breed of $billionaire media owners with a different consciousness about the world and it's history.
Africa will have to become a world superpower.
Black folks must develop a very strong economic base.
Black parents & kids must change their attitudes towards education - no more soft sciences, it's all about the hard sciences or we perish!

Only then will the truth of world history and Africa's role in human upliftment even begin to be accepted.
That's my take!
