Why dream of a better future?

“Hey, Charlie. Check it out! Look over there. That grass is definitely greener on the other side of the fence.” -Joe the Sheep

Joe, the sheep, has adequate grass on his own side of the fence, but he tells his sheep friend Charlie that if in the future they could go to the other side of the fence the grass would be greener.

We hope the future will be better than the present, yet we write books and make movies about a post-apocalyptic future in which life is difficult and bleak.
