Most of the people will have died and the rest of us will be cannibals. Civilization will have broken down. The few people left will be living in a failed state -- like Somalia or Sudan -- and living conditions will be intolerable.
"[T]he rest of us will be cannibals." -- Ted Turner, the eternal optimist, believes he's going to be an eater rather than the eated.

I don't think you can buy yourself out of a hole Ted. Your money will be worthless and your flesh will be tasty. Why aren't you part of the "most of the people" who will die.
