We want people to take care of themselves. We want people to provide for themselves. We want people to enjoy the fruits of their labors. We want people to enjoy reaching out and making their dreams come true. We want people to realize their life's dreams and passions. You need a growing economy for this.
Nowhere in space will we rest our eyes upon the familiar shapes of trees and plants, or any of the animals that share our world. Whatsoever life we meet will be as strange and alien as the nightmare creatures of the ocean abyss, or of the insect empire whose horrors are normally hidden from us by their microscopic scale.
