Near on 8 billion humans rely on the most competent people in the most competent countries to develop the produce and infrastructure to feed them. What happens when we say competence is racist / sexist etc? If we don't reward but instead punish the competent and push them out of these necessary positions?
Well you know how in Zimbabwe, North Korea, Soviet Russia and Venezuela how they threw all the competent farmers off the land? Like what they are doing in South Africa now? Tens of Millions died. Now imagine that world wide.
The business is a microcosm of the global politics. If the competent are replaced with diversity than the system breaks down. If enough vital systems break down society stops functioning. If Western society stops functioning tens of millions who (wrongly) rely on our aid will perish unless they flood the West to scavenge the last remaining resources.
Diversity over Meritocracy is mass suicide.
