There are not, have never been, enough white people in the human race for the global system of White Supremacy to be sustained without the enthusiatic support it currently gets from nonwhite people.
As long as there are as many nonwhite people as we have now who are willing to work for white people in careers such as law enforcement, the military, banking, politics, ... well, really, any profession which is dominated by white decision makers --- we will have the global system of White Supremacy.
It ain't necessary to remove white people from the face of the planet as Dr. Kamau once articulated:
All that is necessary is to remove white people's dominant influence from the face of the planet. That would actually be quite easy, thanks to the fact [think of it as Karma] that white people have always had a much lower birth rate than nonwhite people.
But, to ge rid of white people's dominance, nonwhite people would first have to get over the illusion that success in life requires acquiral of Massa's money. Fiat [synonymous with fake] currency ain't real wealth. And fractional banking is built upon, quite literally, smoke and mirrors.
