Because last time Whites tried to build their own banks and media Dajews started a world war and among other things convinced USA to attack Germany.
Others that tried the same thing are Libya and Syria. Just to mention 2 reason events. And we all know how that ended.
Also the black victim mentality are not the same thing and the slave owners where not white they were Jewish. Then when it suits them they are Jews and gladly let Whites take the blame for their own actions.
