Create projects that you know will fail or run over budget assign all the niggers to them and make a big song and dance about their projects being "so diverse and progressive", assign your most SJW managers to them. Make them review everything they do for its impact on "diversity and inclusion", to the point where nothing ever gets done. base employee job progression on project performance metrics then let all the jews in HR take the blowback for hiring so many IQ defectives, as you quietly point to a pie chart showing which departments have all the failing projects. Keep the low key bread and butter projects for Whites, make sure that any issues they have are ironed out quickly, that they never have to reply on nigger projects to complete, and their pay level attracts more top candidates. You never have to point out race, you just allow the niggers to fail harder, eventually you'll only have Whites left.
