Or we could equally say that without white men there would be hundreds of rampant diseases that were (historically) cured by white scientists, or that without white people there would be even more diseases, or that without white people the economy of the world would be much lower and poverty much higher (because, historically, the economy of the world grew through industrialization, something that white people made).
See, anyone can speculate. So why isn't your post disgusting? The person you quoted used historical facts. You used speculation that cannot be proven AT ALL, but is also illogical if one considers historical fact.
