It's because billionaires are planning on living forever.
When you are going to live forever you won't be able to keep it a secret.
Controlling 10 billion people is much different than trying to control 30 billion.
When illness and death is no longer a concern for you, your only concern will be dying at the hands of another person.
Forever is a long time.
They want the whole planet.
Probably for the same reason I am, there's too many low IQ violent breeders who want welfare and will kill you because you don't have the same skin color or tatoos they have.
That's it. They will keep you for wageless work. I wonder who they think has the low iq, you or I;)
