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.
That's it. They will keep you for wageless work. I wonder who they think has the low iq, you or I;)
