I don't think it is to kill us off. The WEF and all who are a part of it want to kill people off by not by any specific race (maybe, who knows). They want a smaller and more controllable population. One that is just big enough so that if they work non-stop they can support the oligarchs in the lifestyle they demand while the rest of us live in abject poverty.
The irony of Marxism is that it creates an imaginary divide between the oppressed and oppressor class. Then claims to fix it through equality. And as it always turns out Marxism IS the oppressed and oppressor class. It is not just the workers vs the business owners or rich vs poor or white vs non-white like they have been saying for decades now. It is and always will be the oligarchs (the oppressors) and the collective (the oppressed). Marxism can work no other way.
