Really? Do you have any evidence that the countries actually received this money?

Which money? The "20-to-1" return is an attempt to say that if you keep a person alive, their contribution to their economy is going to be much higher than the cost of keeping them alive and healthy.

It beyond improbable given Gates has doubled his net worth since leaving Microsoft.

He left Microsoft as a chairman. He still has a significant amount of holdings (shares). Anyone who has had Microsoft share for a few years, has more than doubled their money. [And I'm not saying that this is a healthy economy.]

Any comments on the ID2020? Or the: Luciferace? Digital currency/transaction surveillance? Eugenics legacy? Vaccine "Final solution"??? Do you have any sources?

No, I neither have more comment nor more sources. I do not do research on Bill Gates. I have my own opinion of him, but I'm not in a position to propagate my opinion or try to educate others.

What I do know, however, is that, providing information out of its context (referring to the example I mentioned in my previous comment) is not the way to educate people or make a "documentary". Even if Bill Gates is truly the most evil person in the world, this sort of out-of-context information is dishonest.
