These things aren't a joke. A vision of absolute power is absolutely corrupting of vision. If the facts seem to fail you, try historical analogy. What the heck, at least it's vivid. Practically anything beats depending on Scripture.
Demographics really count.
All the people who are going to run the world in 20 years are alive right now. The future is always overplayed in five years. This is known as hype. If the topsoil goes, it all goes. If the future were really predictable, we'd all hang ourselves right after killing our children.
